SECT. 9.—DEMONSTRATION OF THE CATHOLIC THEORY
The Catholic theory that Revelation is transmitted and communicated by means of envoys and teachers accredited by God, is evident à priori, i.e. the consideration of the nature of Revelation and its object shows that no other theory is practically possible. There are, however, other proofs also, which are set forth under the following headings:—

1. The documentary proof of the institution of a teaching Apostolate is found in Holy Scripture exactly where we should expect to find it, viz. at the end of the Gospels and at the beginning of the Acts of the Apostles.
(a) The first Evangelist, St. Matthew (28:18, 19), gives the narrative around which all the others group themselves.
