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.
Now they who have attempted to set forth these things in order have laboured by themselves, and have not succeeded in what they attempted. For without the assistance of man come the gifts and the grace of God, which, when it is infused, is wont so to flow, that the genius of the writer is not exhausted, but ever abounding. He well says therefore, Of things which have been fully accomplished among us, or which abound among us. For that which abounds is lacking to none, and no one doubts about that which is fulfilled, since the accomplishment builds up our faith, and the end manifests it.
