Tertullian

“ The injunction is given me not to make mention of any other god, not even by speaking,—as little by the tongue as by the hand,—to fashion a god, and not to worship or in any way show reverence to another than Him only who thus commands me, whom I am both bid fear that I may not be forsaken by Him, and love with my whole being, that I may die for Him. ”

“ But, for our part, contending elsewhere about God, and about all the rest of the body of heretical teaching, we now draw before us definite lines [1] for one form of encounter, maintaining that this will, such as to have given occasion for martyrdoms, is that of not another god than the God of Israel, on the ground of the commandments relating to an always forbidden, as well as of the judgments upon a punished, idolatry. ”

“ At present (it is important) , for we are getting severely stung concerning the will of God, and the scorpion repeats the prick, denying the existence of this will, finding fault with it, so that he either insinuates that there is another god, such that this is not his will, or none the less overthrows ours, seeing such is his will, or altogether denies this will of God, if he cannot deny Himself. ”
