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
Justin MartyrGod called Abraham and commanded him to go out from the country where he was living. With this call God has roused us all, and now we have left the state. We have renounced all the things the world offers.... The gods of the nations are demons.
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 MartyrBut I and others, who are right-minded Christians on all points, are assured that there will be a resurrection of the dead, and a thousand years in Jerusalem, which will then be built, adorned, and enlarged, [as] the prophets Ezekiel and Isaiah and others declare.
Justin MartyrAnd 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.
Justin Martyr
