Sound doctrine does not enter into the hard and disobedient heart; but, as if beaten back, enters anew into itself.

For I choose to follow not men or men's doctrines, but God and the doctrines [delivered] by Him. For if you have fallen in with some who are called Christians, but who do not admit this [truth], and venture to blaspheme the God of Abraham, and the God of Isaac, and the God of Jacob; who say there is no resurrection of the dead, and that their souls, when they die, are taken to heaven; do not imagine that they are Christians

Let it be understood that those who are not found living as He taught are not Christian- even though they profess with the lips the teaching of Christ.

No one who is rightly minded turns from true belief to false.

We expect to receive again our own bodies, though they be dead and cast into the earth, for we maintain that with God nothing is impossible.

And this food is called among us the Eucharist, of which no one is allowed to partake but the man who believes that the things which we teach are true, who has been washed with the washing that is for the remission of sins and to regeneration, and who is so living as Christ has enjoined.

If some should accuse us as if we held that people born before the time of Christ were not accountable to God for their actions, we shall anticipate and answer such a difficulty. We have been taught that Christ is the first-begotten of God, and we have declared him to be the Logos of which all mankind partakes. Those, therefore, who lived according to reason (logos) were really Christians, even though they were thought to be atheists, such as, among the Greeks, Socrates, Heraclitus and others like them.
