The Arians are condemned by the Holy Spirit through the mouth of David: for they dare to limit Christ’s knowledge. The passage cited by them in proof of this is by no means free from suspicion of having been corrupted. But to set this right, we must mark the word “Son.” For knowledge cannot fail Christ as Son of God, since He is Wisdom; nor the recognition of any part, for He created all things. It is not possible that He, who made the ages, cannot know the future, much less the day of judgment. Such knowledge, whether it concerns anything great or small, may not be denied to the Son, nor yet to the Holy Spirit. Lastly, various proofs are given from which we can gather that this knowledge exists in Christ.
