Because 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 MartyrNow bring what we have into common stock, and communicate to everyone in need; we who hated and destroyed one another, and on account of their different tribe, now since the coming of Christ, live familiarly with them, and pray for our enemies, and endeavor to persuade those who hate us unjustly, to the end that they may become partakers of the same joyful hope of a reward from God the ruler of all.
Justin MartyrIf you are eagerly looking for salvation, and if you believe in God, you may ... become acquainted with the Christ of God, and, after being initiated [a reference to baptism], live a happy life.
Justin MartyrWhen we say that Jesus Christ was produced without sexual union, was crucified and died, and rose again, and ascended to heaven, we propound nothing new or different from what you believe regarding those whom you call the sons of Jupiter.
Justin Martyr... it is better to believe even what is impossible to our own nature and to men, than to be unbelieving like the rest of the world, we have learned; for we know that our Master Jesus Christ said, that 'what is impossible with men is possible with God' (Mt. 19:26)?
