Tertullian, on Phil 3:13

“Brethren, I do not count myself to have apprehended. But one thing I do: forgetting the things that are behind, and stretching forth myself to those that are before,”

“Yet I must necessarily prescribe you a law, not to stretch out your hand after the old things, not to look backwards: for "the old things are passed away," according to Isaiah; and "a renewing hath been renewed," according to Jeremiah; and "forgetful of former things, we are reaching forward," according to the apostle; and "the law and the prophets (were) until John," according to the Lord.”
