The Spirit of Christ which was in them—First, "who was in them," and secondly, "testifying," that is, giving a testimony, by which expression he intimates that the prophets were endued with the Spirit of knowledge, and indeed in no common manner, as those who have been teachers and witnesses to us, and that yet they were not partakers of that light which is exhibited to us. At the same time, a high praise is given to their doctrine, for it was the testimony of the Holy Spirit; the preachers and ministers were men, but he was the teacher. Nor does he declare without reason that the Spirit of Christ then ruled; and he makes the Spirit, sent from heaven, to preside over the teachers of the Gospel, for he shews that the Gospel comes from God, and that the ancient prophecies were dictated by Christ.
