"Christ did not found an abstract religion, a mere school of religious thought. He setup a community of apostles, of teachers, with the task of spreading His message and so giving rise to a society of believers: His Church. He promised the Spirit of truth to His Church and then sent Him."

Seeing there are many who think they hold the opinions of Christ, and yet some of these think differently from their predecessors, yet as the teaching of the Church, transmitted in orderly succession from the apostles, and remaining in the Churches to the present day, is still preserved, that alone is to be accepted as truth which differs in no respect from ecclesiastical and apostolica tradition.
