There are two ways, one of life and one of death, and there is a great difference between these two ways.
The Way of Life
Now this is the way of life: First, you shall love God, who made you. Second, you shall love your neighbor as yourself; but whatever you do not wish to happen to you, do not do to another. The teaching of these words is this: Bless those who curse you, and pray for your enemies, and fast for those who persecute you. For what credit is it if you love those who love you? Do not even the Gentiles do the same? But you must love those who hate you, and you will not have an enemy. Abstain from fleshly and bodily cravings. If someone gives you a blow on your right cheek, turn to him the other as well and you will be perfect. If someone forces you to go one mile, go with him two miles; if someone takes your cloak, give him your tunic also; if someone takes from you what belongs to you, do not demand it back, for you cannot do so.
Give to everyone who asks you, and do not demand it back, for the Father wants something from his own gifts to be given to everyone. Blessed is the one who gives according to the command, for such a person is innocent. Woe to the one who receives: if, on the one hand, someone who is in need receives, this person is innocent, but the one who does not have need will have to explain why and for what purpose he received, and upon being imprisoned will be interrogated about what he has done, and will not be released from there until he has repaid every last cent. But it has also been said concerning this: “Let your gift sweat in your hands until you know to whom to give it.”
The second commandment of the teaching is: You shall not murder; you shall not commit adultery; you shall not corrupt children; you shall not be sexually immoral; you shall not steal; you shall not practice magic; you shall not engage in sorcery; you shall not abort a child or commit infanticide. You shall not covet your neighbor’s possessions; you shall not commit perjury; you shall not give false testimony; you shall not speak evil; you shall not hold a grudge.… You shall not hate anyone; instead you shall reprove some, and pray for some, and some you shall love more than your own life.
The Way of Death
But the way of death is this: First of all, it is evil and completely cursed; murders, adulteries, lusts, sexual immoralities, thefts, idolatries, magic arts, sorceries, robberies, false testimonies, hypocrisies, duplicity, deceit, pride, malice, stubbornness, greed, abusive language, jealousy, audacity, arrogance, boastfulness. It is the way of persecutors of good people, of those who hate truth, love a lie… have no mercy for the poor, do not work on behalf of the oppressed, do not know the one who made them, are murderers of children, corrupters of God’s creation, who turn away from someone in need, who oppress the afflicted, are advocates of the wealthy, lawless judges of the poor, utterly sinful. May you be delivered, children, from all these things!
See that no one leads you astray from this way of the teaching, for such a person teaches you without regard for God. For if you are able to bear the whole yoke of the Lord, you will be perfect. But if you are not able, then do what you can.
