'That there exists in the human mind and indeed by natural instinct, some sense Deity [sensus divinitatis], we hold to be behind dispute, since God himself, to prevent any man from pretending ignorance, has endued all men with some idea of his Godhead ... this is not a doctrine which is first learned at school, but one as to which every man is, from the womb, his own master; one which nature herself allows no individual to forget' (Calvin, Institutes of the Christian Religion)
