Cosmas Indicopleustes, on Rom 1:21

“Because that, when they knew God, they have not glorified him as God, or given thanks; but became vain in their thoughts, and their foolish heart was darkened.”

“Although they have received a copious language and an elegant mode of speech from the bounty of God, yet, being unthankful to God the Giver, they are disobedient to His words; and while they have received everything from God and their predecessors, they set them aside, and with swaggering insolence ascribe everything to themselves.”
