Ambrose of Milan
Catena Aurea · Lukasevangelium 1
Forasmuch as many have taken in hand to set forth in order a declaration of those things which are most surely believed among us, Even as they delivered them unto us, which from the beginning were eyewitnesses, and ministers of the word: It seemed good to me also, having had perfect understanding of all things from the very first, to write unto thee in order, most excellent Theophilus, That thou mightest know the certainty of those things, wherein thou hast been instructed.
(Expos. Ev. Luc. l. i. c. i.) For as many among the Jewish people prophesied by inspiration of the Spirit of God, but others were false prophets rather than prophets, so now also have many attempted to write Gospels which the good moneychanger refuses to pass. One gospel is mentioned which the twelve Apostles are said to have written; another Basilides presumed to write; and another is said to have been by Matthias.
