Homilies on the Gospel of John

“It is written in your Law, that the testimony of two men is true.”

3. What would the heretics say here? (They would say,) “How is he better than man, if we take what he has said simply? For this rule is laid down in the case of men, because no man by himself is trustworthy. But in the case of God, how can one endure such a mode of speaking? How then is the word 'two' used? Is it because they are two, or because being men they are therefore two? If it is because they are two, why did he not betake himself to John, and say, I bear witness of myself, and John bears witness of me? Wherefore not to the angels? Wherefore not to the prophets? For he might have found ten thousand other testimonies.” But he desires to show not this only that there are Two, but also that they are of the same Substance.
