Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfill.
All Commentaries on Matthew 5:17 Go To Matthew 5
Augustine of Hippo
AD 430
And therefore, after He has exhorted His hearers that they should prepare themselves to bear all things for truth and righteousness, and that they should not hide the good which they were about to receive, but should learn with such benevolence as to teach others, aiming in their good works not at their own praise, but at the glory of God, He begins now to inform and to teach them what they are to teach; as if they were asking Him, saying: Lo, we are willing both to bear all things for Your name, and not to hide Your doctrine; but what precisely is this which Thou forbiddest us to hide, and for which You command us to bear all things? Are You about to mention other things contrary to those which are written in the law? No, says He; for think not that I have come to destroy the law, or the prophets: I am not come to destroy, but to fulfil.
