"The fact that even after Vatican II authors repeatedly referred to Franzelin meant that the work of Franzelin himself must be studied in depth in order to make any claim that one has done the proper research to speak with any authority on the topic of Tradition."

-Fr. Chad Ripperger, PhD

Cardinal Franzelin was a peritus at the First Vatican Council, and was made a Cardinal by Bl. Pope Pius IX. He was also an expert in Hebrew and a lecturer in Chaldean and Syriac. His lectures and theological writings held first place in the Roman Theological scene of his day.

In 26 Theses, Cardinal Franzelin challenges the Protestant notion that Tradition is opposed to Scripture, by a direct analysis of the establishment of a living magisterium in Scripture, and the witness to this magisterium given by the Fathers of the Church and all Christian ages.
