Paulist Fathers, Sermons by the Fathers of the Congregation of St…
“ It follows that the communion of which the Pope is the Supreme Head, is the true Church established by Jesus Christ—One, Holy, Catholic, and Apostolic, incapable of falling away, and infallible in doctrine. The foundation of this great and world-wide Church is the Papal Supremacy of St. Peter and his successors, and its principal portion is the Roman See. If I prove that this foundation was laid by Jesus Christ, it will be evident that the Church founded upon it is the true Catholic Church, and the faith of that Church the true Christian and Catholic faith. ”
