Tertullian

“ For what man would be long in learning, that he ought to pursue a new discipline, after he had taken up with a new god? Since, however, [7] the same God was declared in the gospel which had always been so well known in the law, the only change being in the dispensation, [8] the sole point of the question to be discussed was, whether the law of the Creator ought by the gospel to be excluded in the Christ of the Creator? ”

“ The epistle which we also allow to be the most decisive [1] against Judaism, is that wherein the apostle instructs the Galatians. For the abolition of the ancient law we fully admit, and hold that it actually proceeds from the dispensation of the Creator,—a point which we have already often treated in the course of our discussion, when we showed that the innovation was foretold by the prophets of our God. ”

“ It is because they declare no other God than the Creator, and prove Christ to belong to no other God than the Creator; whilst the promise of the Holy Ghost is shown to have been fulfilled in no other document than the Acts of the Apostles. ”
