Thomas Aquinas, on 1Thess 2:10

“You are witnesses, and God also, how holily, and justly, and without blame, we have been to you that have believed:”

“Then when Paul says: you are witnesses, he remarks on the orthodoxy of his discourse. First, he speaks about the sanctifying influence it may have on a person's life; secondly, he shows how full of concern his teaching was (2:11). So Paul remarks: you are witnesses how holy, that is, how innocently, we conducted ourselves: "Be holy, for I am holy" (Lev. 11:44 and 19:2); and righteous toward our neighbor, as is made evident by "to live sober, upright and godly lives in this world" (Tit. 2:12); and blameless was our behaviour to you believers, which means that you believed because we have done nothing that could have caused anyone to be scandalized. To you believers, individually. It should be noted that sometimes a singular predication has considerable import.”
