Tertullian

Now, if the Creator indeed promised that "the ancient things should pass away," to be superseded by a new course of things which should arise, whilst Christ marks the period of the separation when He says, "The law and the prophets were until John" -thus making the Baptist the limit between the two dispensations of the old things then terminating-and the new things then beginning, the apostle cannot of course do otherwise, (coming as he does) in Christ, who was revealed after John, than invalidate "the old things" and confirm "the new," and yet promote thereby the faith of no other god than the Creator, at whose instance it was foretold that the ancient things should pass away.

"If therefore any man be in Christ, he is a new creature; old; things are passed away; behold, all things are become new; " and so is accomplished the prophecy of Isaiah.

All the rest of his precepts, as we have shown sufficiently, when treating of them as they occurred in another epistle, emanated from the Creator, who, while predicting that "old things were to pass away," and that He would "make all things new," commanded men "to break up fresh ground for themselves," and thereby taught them even then to put off the old man and put on the new.
