Theophylact of Ohrid, 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:”

“God is a trustworthy witness, but since people do not know whether God testifies to this, he also calls as witnesses those to whom the word is addressed. Fulfilling all that is required, for this is the meaning of "holy," in place of the expression: with the fear of God. That is, not extorting money from anyone – demanding exactions of money. Not offending and not giving occasion for stumbling. Then whereas among the unbelievers the apostle was called godless and a deceiver, a babbler and utterly senseless.”
