Calvin on Scripture’s Testimony to God

Scripture’s Testimony to God: Institutes I:11:1

1.We are forbidden every pictorial representation of God

As Scripture, in accommodation to the rude and gross intellect of man, usually speaks in popular terms, so whenever its object is to discriminate between the true God and false deities, it opposes him in particular to idols; not that it approves of what is taught more elegantly and subtilely by philosophers, but that it may the better expose the folly, nay, madness of the world in its inquiries after God, so long as every one clings to his own speculations. This exclusive definition, which we uniformly meet with in Scripture, annihilates every deity which men frame for themselves of their own accord – God himself being the only fit witness to himself.
