This monumental liturgical work, comprising fifteen volumes, was the life-long labor of Benedictine Abbot Dom Guéranger. Written with the heart of a seraphic contemplative, the holy abbot takes the reader on a daily spiritual pilgrimage through the liturgies of both the East and the West as he immerses the soul into the very life of the ecclesia orans et adorans (the church praying and adoring). The author achieves this by providing daily entries corresponding to the yearly cycle of the Church’s worship in both her divine seasonal feasts and those of her saints. Each day begins with a rich and provocative meditation on the mystery of faith to be celebrated together with the ecclesial history of the same; this is followed by excerpts from the Roman Missal’s Mass of the day (complete with Propers, i.e., Introits, Collects, Offertory prayers, etc ) as well a host of exquisite hymns from the divine office which are coupled with varied and sundry sequences garnered from other ancient Catholic rites.

The temporal and geographical universality of the Church is thusly honored; and the oneness of faith amply manifested in light of the axiomatic criterion: Lex orandi est lex credendi (the law of praying is the law of believing). If the essence of the Holy Mass is God, the Incarnate Victim, offering Himself to God, then the liturgy of the Mass is man, in union with Jesus Christ (per ipsum, et cum ipso, et in ipso), offering God to God. Truly, here is a priceless treasure awaiting your holy exploitation. Such was the strategy employed by the father of Saint Therese of Lisieux who made it a daily routine in the Martin home to read to his five daughters from these very volumes.

This Loreto edition is the only complete edition available, with all of the deleted material that is missing from other American editions restored by Loreto.

Louis Veuillot - PB 146 pages

Louis Veuillot’s mid-19th century condemnation of liberal Catholicism throws a flood of light on the crisis of Church and world following on the Second Vatican Council. Catholics who read “The Liberal Illusion” will grasp, once and for all, that the crisis is primarily due not to Vatican II, but to a centuries-long struggle between Revelation and Revolution. Vatican II was merely a decisive moment in that struggle when power within the Church passed from the servants of Revelation to the deluded victims of the Revolution.

Fr. Denis Fahey C.S.Sp. - PB 212 pages

“I repeatedly promised Saint Peter that if I ever got the chance, I would teach the truth about his Master in the way he and his successors, the Roman Pontiffs, wanted it done. That is what I have striven to do and am doing.”    
—Rev. Denis Fahey

No man is wise who does not think correctly about the Jews. On this subject it is very easy to be wrong, and there are many different varieties of errors into which to fall.  They are a unique type of collectivity—a matter for history, not for sociology.
Their election in the Old Testament, which we must accept on faith, is at least as mysterious as their rejection in the New Testament. The Jews are willing to take the first part of the bargain, which they did not deserve, but not the second, which they did. Ever since the moment of the Crucifixion, the Jews are engaged in a mystical war against the Church, but they are only effective when the Faith is weak.
A true, firm, and unsentimental understanding of the Jewish problem is absolutely necessary for one who must protect the Faith and the faithful. The higher the responsibility, the greater the necessity.
Fr. Fahey begs us to pray for the Conversion of the Jewish nation, but he teaches us to prudently study and to wisely understand reality in their regard.

“I repeatedly promised Saint Peter that if I ever got the chance, I would teach the truth about his Master in the way he and his successors, the Roman Pontiffs, wanted it done. That is what I have striven to do and am doing.”    —Rev. Denis Fahey

This book is the first published by Fr. Denis Fahey, the great apostle of the Kingship of Christ in the 20th century. In it he lays down the essential philosophical and theological principles that undergird and enliven the entire published corpus of his life’s work in defense of the Social Rights of God, in direct opposition to the nefarious Declaration of the Rights of Man that was the published declaration of war against Catholic civilization issued by the “enlightened” Freemasons who were responsible for the French Revolution.

The war that Fr. Fahey so clearly delineated and chronicled is still engaged, even though few Catholics understand the nature and the extent of this war against human society and especially against Our Lord in His Mystical Body, the Catholic Church. The two ancient battle cries “We will not have this Man rule over us!” and “Non Serviam!” have been vividly revived in the 20th century by a host of enemies of Christ’s Kingship over human society. Until all human society—especially national governments—publicly recognize that Kingship, civilization will continue on its downward spiral.

We hope that the re-publication of Fr. Fahey’s works will assist the Faithful in their attempts to restore all things in Christ for the future of our children and our children’s children and for the Greater Glory of God!

By Fr. John J.  Hugo - PB - 176 pages

Fr. John Hugo (1911–1985) was a priest of the Diocese of Pittsburg who spent much of his life giving retreats based upon those that he had participated in while still a young priest in the 1930s. Those retreats were given by Fr. Onesimus Lacouture S. J. and Fr. Hugo was one of over 6000 priests to whom the retreat was given over a course of several years. The Retreat, as it was affectionately called by its devoteés was an electrifying and life-changing experience for many of them. It was nothing more nor less than the Spiritual Excercises of Saint Ignatius. But these retreats given by Fr. Lacouture were, as the saying goes “the real deal.” They were given as St. Ignatius intended, for the proper length of time and according to the true Ignatian spirit. They got to the real “roots” of Christian living. They were, in short, radical.

Fr. Hugo became a disciple of Fr. Lacouture in the sense that he experienced the fruits and saw the necessity of the retreat for Catholic Americans. He determined to continue that work as part of his priestly vocation. Fr. Hugo became the spiritual advisor of Dorothy Day (and the Catholic Worker Movement) who took the retreat more than twenty times during her life.
This book, The Gospel of Peace, is one fruit of that work, and it was very controversial at the time of its publication in 1943. The Gospel of Jesus Christ is always controversial because it is “out of step” with the world.

Don Pietro Leome - PB 246 pages

In our days the war against God and His Church has become deeper and broader than at any time in history. No longer are the powers of darkness content to attack only the institutional Church that God founded. The truth is that the human nature that God the Father created is now the subject of the adversary’s most violent persecution, and through the undermining of the very concept of human nature and the natural law enshrined in it the enemies of God hope to make any consideration of the concept of  ‘super-nature’ and super-natural life disappear from the minds of men.

The Church has always been the true guardian of not only supernatural life, but of the natural law as well. Since the natural law is the law that God put into our nature and it is discernible in the light of reason, the Church, speaking for God, is the champion of sound reasoning. With the natural law as well as supernatural law governing human sexuality and family life under attack, Don Pietro Leone has risen to defend (and to properly distinguish) those areas, so that those who wish to defend the Church and human society in our age may have sound teaching upon which to base their actions.

In the course of this treatment of these topics he makes a detailed critique of certain novel presentations of themes found in the Magisterium from the time of the Second Vatican Council onwards. Amongst these doctrines is one he terms ‘Magisterial Personalism’ and another called the ‘Theology of the Body.’ Drawing upon scholastic philosophy and the perennial teaching of the Church, Don Pietro brings light to a subject recently plunged into obscurity and darkness that is not currently being dispelled sucessfully, even by the guardians of Truth themselves.

Don Pietro Leone - PB 122 pages

Don Pietro Leone is the author of this most useful summary of the history of the destruction of the Roman rite and the substitution of a modern rite called the Novus ordo (new order) in its place. In his General Audience of November 9, 1969, Pope Paul VI had this to say (among many other things) about substitution of the new rite for the Roman rite of all times: “This change has something astonishing about it, something extraordinary. This is because the Mass is regarded as the traditional and untouchable expression of our religious worship and the authenticity of our faith.”
No truer words were ever spoken by a pontiff, except perhaps by the high priest who once said: “You know nothing. Neither do you consider that it is expedient for you that one man should die for the sins of the people and that the whole nation perish not.”
Some, upon contemplating these extraordinary changes, go so far as to think that the attempts of the Church’s enemies to eradicate once and for all “Popish superstition” from the world have made significant progress towards their goal when the Pope himself allowed the introduction of, in his own words, “a new rite” into the heart of the Church. Others seek to understand God’s will in these matters and consider that these changes and the resulting chaos in the life of the Church might be among those vague “chastisements” mentioned by Our Lady at Fatima. Still other observers of the Church in the latter half of the 20th Century and into the third millennium believe that the new mass is a great development of human progress and is the harbinger of a new “springtime” in the life of the Mystical Body, while yet others, many of the lay-faithful, struggle to maintain their faith and to live the life of faith somewhat passively in a spirit of docility in the face of the radical changes in liturgy and the life of the Church. Countless others have just dropped out of the daily life of the Church altogether.
There is no question that the new rite has changed the Church. This little book seeks to serve as a scholarly and objective summation of the changes and their effects. The substance of the work is taken largely from the mouths of those who were responsible for promoting and producing the changes as well as from several lengthy and scholarly books published by those who oppose them.

The Canons and Decrees of Trent and Vatican I - In Latin and English - PB 170 pages

Here you will find all of the essential documents and infallible teachings of these two modern councils of the Catholic Church. They are beautifully laid out in a two-column format with large readable fonts  of both the original Latin and Cardinal Manning's English translation side by side.

Foreword

To say that the Catholic world is in a state of doctrinal confusion today would be an almost comical understatement, were not the issues involved—the individual salvation or damnation of every man, woman, and child on the planet—so important. Despite the wealth of defined dogmatic teaching that the Church has produced over twenty centuries, the actions of many prelates, priests, and theologians (some in the highest reaches of the hierarchy) have obscured the truths of the Faith for many, if not most, Catholics and non-Catholics.
This has happened before. In the 16th century, the successive revolts of Martin Luther, John Calvin, and Henry VIII and their brethren, together with pre-existing abuses and doctrinal questions that opened the door for their defections, created an enormous amount of confusion in the Church. All areas of Catholic life—pastoral, devotional, and liturgical—suffered. As kings and princes began to create their own state churches and enforce membership in these fake churches on their hapless subjects, Pope Paul III (1534–1549) decided, in concert with Holy Roman Emperor Charles V, that the time had come to call a new Ecumenical Council. This was slated to air Protestant complaints, reform Catholic practices, define or redefine disputed dogmas, and reconcile Christian princes, with a view to uniting Christendom and reviving the Crusades. Pope and Emperor agreed that it would convene at Mantua on May 23, 1537. Renewed war broke out between the Emperor and the French, thus delaying the opening. Two years of delays led the Pope to cancel the whole process.
Emperor Charles V, however, was very keen on the idea, and on December 13, 1545, the Council at last convened at the city of Trent. The seat of a Prince-Archbishopric of the Holy Roman Empire, it was Charles’ choice for the Council’s location. During the next few years in eighteen sessions, doctrinal decrees would be issued on the Holy Scriptures, Original sin, Justification, the Sacraments in general, Baptism, and Confirmation. An outbreak of the plague and various other things, including Paul III’s death, led to the Council being prorogued indefinitely on September 17, 1549.
The new Pope, Julius III (1550–1555), agreed with Charles V that there should be no further delay. The Council Fathers gathered at Trent on May 1, 1551. The Emperor and Pope concurred that the Protestants should appear at the Council and present their case—although without being able to vote. Although some of the Reformers did set out for the Council, in the end none appeared because of their inability to vote. Nonetheless, important work was done, and decrees defining Catholic teaching on the Holy Eucharist, Penance, and Extreme Unction were passed by the delegates. Unfortunately, at this juncture, the Emperor’s war against the Protestants took a turn for the worse, and Maurice, the Elector of Saxony invaded Tyrol. The Council was broken up by the threat on April 28, 1552. As Julius III retreated ever more into his strange interests, the prospect of reconvening the Council receded, while his successor, the stern reformer Paul IV, had other fish to fry in clearing out from Rome the moral detritus left by Julius. Moreover, Charles V had abdicated in 1555; his brother and successor as Holy Roman Emperor, Ferdinand I, was not as interested in Council as his brother had been—at least initially.
Pius IV (1559-1565) was determined that the council should be reopened and brought to a successful conclusion. From January 18, 1562 to December 4, 1563, the Council met at Santa Maria Maggiore, and continued until its final adjournment on 4 December 1563. The final doctrinal decrees were on Matrimony; Cults of Saints, Relics, and Images; and at last the very topic that had excited Luther so much way back in 1517: Indulgences. The documents were signed at last by 255 Council Fathers, and the bull of ratification was published by the Pope on January 26, 1564.
The Council had asked the Pope to continue its work by publishing definitive versions of a catechism based upon its decrees; shepherded through by Pius IV’s nephew, St. Charles Borromeo, this appeared in 1566, and remains today as the most clear, unambiguous, and authoritative catechism in print. Having appeared under St. Pius V, the catechism was soon joined by revisions of the Breviary and Missal, the latter of which remained substantially unchanged until the mid-20th century.
Almost two centuries later in the 18th century, the Catholic world had changed considerably. On the one hand, Latin America, the Philippines, and various other new regions had been added to the Church; but on the other Protestantism had solidified into its own bloc of nations, the Enlightenment and the French and succeeding Revolutions had toppled Monarchs, and there was no more Holy Roman Emperor. Scientism and Socialism were sapping the faith even of Catholics—and the supposedly Catholic government of the new Italian Kingdom was struggling with the Papacy for control of the remainder of the Papal States. At any moment, Bl. Pope Pius IX (1846-1878) faced an imminent invasion of his own capital, Rome.
The many struggles around the world between Catholics and governments intent on usurping the rights of the Church in various ways were at once symbolized by and subsumed into the one the Pope faced. This fact, combined with the spread of the telegraph, newspapers, and steamships put the Pope very much into the forefront of the Church’s worldwide struggle. The Ultramontanist party in every Catholic land called for the closest possible unity between the national Churches and the Holy See and with each other. In the face of all of this, Bl. Pope Pius IX convoked an Ecumenical Council, Vatican I.
Although they all refused in varying tones from polite to contemptuous, all of the Eastern Orthodox Patriarchs had been invited as full participants to the Council by the Pope as an attempt to end the Eastern Schism.
Opening on December 1869 at St. Peter’s Basilica rather than the Lateran (where the prior five councils in Rome had met) and adjourned on October, 20 1870, a month after the Italians at last conducted their long-threatened seizure of Rome, Vatican I accomplished far less than Trent. Nevertheless, it did deal definitively with two important matters. The first—the pretended clash between Faith and Reason, which Liberalism had pushed to the forefront of national life in so many countries—was dealt with in the Dogmatic Constitution on the Catholic Faith (Dei Filius). Far more controversial and hotly debated at the time was the dogma of Papal Infallibility, at last defined in the First Dogmatic Constitution on the Church of Christ (Pastor aeternus). The Council was then prorogued. It would not be officially concluded until the eve of Vatican II.
Much of course has changed since then. But what has not changed is the essential nature of these defining documents. Regardless of changes in technology, fashion, liturgy, or anything else, these pages contain the bare minimum of what it is to be Catholic: if one can read it all and agree with it all, he is a Catholic; if not, not. In the current period of confusion, a clear guide to spiritual reality such as this is utterly essential; we all owe a debt of gratitude to Loreto Publications for making it available.
