Theophylact of Ohrid, on Rom 3:4

“But God is true; and every man a liar, as it is written, That thou mayest be justified in thy words, and mayest overcome when thou art judged.”

“Above he said that some did not believe. Yet it turns out that not just some, but all proved faithless. Therefore, so as not to grieve the Jews, he speaks wisely and presents what was shown by experience in the form of a supposition. Let us say, he says, that all were faithless. What of it? Even in this case God is justified. That is: if one considers and compares what God bestowed upon the Jews and how they conducted themselves before Him, then righteousness remains on God's side, as David also says (Ps. 50:6).”
