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