The Second Epistle of Clement to the Corinthians

Seeing, then, that he has shewn such mercy[*](Our duty to Christ) towards us, first that we who are living do not sacrifice to the dead gods, and do not worship them, but through him know the father of truth, what is the true knowledge concerning him[*](The Greek is as ambiguous as the English, but this him no doubt refers to the father of truth.) except that we should not deny him through whom we knew him?

And he himself also says, Whosoever confessed me before men, I will confess him before my Father;

this then is our reward, if we confess him through whom we were saved.

But how do we confess him? By doing what he says, and not disregarding his commandments, arid honouring him not only with our lips, but with all our heart and all our mind.

And he says also in Isaiah, This people honoureth me with their lips, but their heart is far from me.
