Bernard Schmid, OSB, with the approbation of the Bishop of Freiburg, freely translated from the 5th German edition by a Benedictine, revised with notes and additions for English readers by Msgr. V.J. [Victor Januarius] Schobel, with Preface by the Right Rev. Bishop J.C. Hedley of Newport (St. Louis, Freiburg, London: B. Herder, 1911). With Imprimatur. May be read online, and available in pdf, mobi/kindle, epub, and other formats at Internet Archive. An earlier edition (St. Louis, Mo.: B. Herder, 1899) is available at Open Library  and Internet Archive (linked by the Free Traditional Catholic Books page of Traditional Catholic), with a 2nd copy at Internet Archive (front pages missing) and a 3rd copy at Internet Archive.
    • [Note: What distinguishes this book from the likewise erudite works of Dr. Otto Bardenhewer and Dr. Joseph Tixeront is the fact that its historical overview of the Fathers is preceded by a general introduction to the field of patrology, as well as a detailed “Introductory and Propadeutical Part” discussing the methodology of patristics: the authority of the Fathers and the way their works are examined, used, and understood.]

“[The Gospel’s] saving truth and rules of conduct… are contained in the written books and in the unwritten traditions… received by the Apostles… dictated either orally by Christ or by the Holy Ghost, and preserved in the Catholic Church in unbroken succession… [N]o one… shall, in matters of faith and morals pertaining to the edification of Christian doctrine, distorting the Holy Scriptures in accordance with his own conceptions, presume to interpret them… contrary to the unanimous teaching of the Fathers.” (Council of Trent, Session IV)

“Christ the Lord in whom the full revelation of the supreme God is brought to completion (…), commissioned the Apostles to preach to all men… [T]he Apostles left bishops as their successors, “handing over” to them “the authority to teach in their own place.”… And so the apostolic preaching… expressed in a special way in the inspired books, was to be preserved by an unending succession of preachers until the end of time… The words of the holy fathers witness to the presence of this living tradition…” (Second Vatican Council, Constitution on Divine Revelation)

Apologia of Demetrios Kydones for Unity with Rome & the ‘Contra Errores Graecorum’ of St. Thomas Aquinas, edited by James Likoudis (New Rochelle, NY: Catholics United for the Faith, 1992), with Imprimatur, which may be purchased on this page of James Likoudis’ page and at Amazon. An incomplete English translation of the first 10 headings of the work, translated by Antoine Valentim, may be read online at the Internet Archive Wayback Machine (linked by Wikipedia). The Latin text may be read online on this page of Corpus Thomisticum (linked by Wikipedia). [Note 1. Despite the polemical title of the text, it has an irenic tone and content. Rather than directly assailing the ideas of the schismatic Eastern churches, it demonstrates that the pre-Photian sources of Eastern theology affirm the teaching of the Catholic Church on points disputed by the schismatic Eastern churches. See James Likoudis’ essay “St. Thomas Aquinas, Defender of the Papacy and the Unity of the Church”.] [Note 2. In his essay “St. Thomas Aquinas, Papal Supremacy, and the Witness of the Eastern Churches in the First Millennium”, James Likoudis discussed objections to St. Thomas’ citations of the Fathers.]

“[I]n order that they may illumine the mysteries of salvation as completely as possible, the students should learn to penetrate them more deeply with the help of speculation, under the guidance of St. Thomas, and to perceive their interconnections.” (Second Vatican Council, Decree “Optatam Totius” on Priestly Training)

“In those schools dependent on her [the Church] intends that… individual subjects be pursued according to their own principles, method, and liberty of scientific inquiry, in such a way… that, as… investigations [are] carefully made according to the example of the doctors of the Church and especially of St. Thomas Aquinas, there may be a deeper realization of the harmony of faith and science.” (Second Vatican Council, Decree “Gravissimum Educationis” on Christian Education)

The Catholic eBooks Project

Provides a library of links to Christian ebooks and texts that may be read online or downloaded LEGALLY and for FREE, and are FAITHFUL to the truths that God entrusted to His one true Church.

The Project is dedicated to the Incarnate Logos:

“In principio erat Verbum, et Verbum erat apud Deum, et Deus erat Verbum… Et Verbum caro factum est, et habitavit in nobis… gratia et veritas per Jesum Christum facta est.” (S. Joannem i, 1, 14, 17)

“Ecce concipies in utero, et paries filium, et vocabis nomen ejus Jesum: hic erit magnus, et Filius Altissimi vocabitur… et regnabit in domo Jacob in æternum, et regni ejus non erit finis.” (S. Lucam i, 31-33)

Prayer for the Church

O God, our refuge and our strength, look down with mercy upon the people who cry to Thee; and by the intercession of the glorious and immaculate Virgin Mary, Mother of God, of Saint Joseph her spouse, of the blessed Apostles Peter and Paul, and of all the saints, in Thy mercy and goodness hear our prayers for the conversion of sinners, and for the liberty and exaltation of the Holy Mother the Church. Through the same Christ Our Lord. Amen. (From the text of the Leonine Prayers after Low Mass at Sancta Missa)
