Sound doctrine does not enter into the hard and disobedient heart; but, as if beaten back, enters anew into itself.
Justin MartyrBecause of this basin of repentance and knowledge of God, which has been ordained for the transgression of God's people, as Isaiah cries, we have believed, and we testify that the very baptism which he announced is alone able to purify those who have repented. It is the water of life. But the cisterns which you have dug for yourselves are broken and of no benefit to you. For what is the use of a baptism which cleanses the flesh and body alone? Baptize the soul from wrath and from covetousness, from envy, and from hatred, and, lo, the body is pure.
Justin MartyrLet 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.
Justin MartyrIn that we say he [Christ] made whole the lame, the paralytic, and those born blind, we seem to say what is very similar to the deeds said to have been done by Esculapius.
Justin MartyrAnd if we even affirm that He was born of a virgin, accept this in common with what you accept of Perseus.
Justin MartyrIf 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.
