An ancient Christian list, which draws from the Jewish Scriptures and the Gospels:

The Lord's Teaching through the Twelve Apostles to the Gentiles
1 There are two Ways, one of Life and one of Death, and there is a great difference between the two Ways.
Truly, the Way of Life is this: First, you shall love the God who made you, second, your neighbour as yourself. And whatever you would not have done to you, do not to another. Now of these words, the Teaching is this: Bless those that curse you, and pray for your enemies, and fast for those that persecute you. For what credit is it to you if you love those that love you? Do not even the Gentiles do the same? But love those that hate you, and you will have no enemy. Abstain from carnal and worldly lusts. If any man smites you on the right cheek, turn to him the other cheek also, and you shall be perfect. If any man presses you to go with him one mile, go with him two. If any man takes your cloak, give him your shirt also. If any man takes from you what is yours, ask not for it again, for you are not even able.
Give to everyone that asks you, and ask not again, for the Father's will is that we give to all from the gifts we have received. Blessed is he that gives according to the commandment, for he is innocent. Woe to him who receives, for if any man receive alms under pressure of need he is innocent, but he who receives without need shall be tried as to why he took and for what, and being in prison he shall be examined concerning his deeds, and he shall not come out from there until he pays the last farthing. But concerning this it was also said: Let your alms sweat into your hands until you know to whom you are giving.
2 The second commandment of the Teaching is this: You shall do no murder, you shall not commit adultery, you shall not commit pederasty, you shall not commit fornication, you shall not steal, you shall not use magic, you shall not use sorcerer’s potions, you shall not murder a child by abortion nor kill it when it is born, you shall not covet your neighbour’s goods, you shall not commit perjury, you shall not bear false witness, you shall not speak evil, you shall not bear malice. You shall not be double-minded nor double-tongued, for to be double-tongued is the snare of death. Your speech shall not be false or empty, but completed in action. You shall not be covetous nor extortionate, nor a hypocrite, nor malicious, nor proud. You shall make no evil plan against your neighbour. You shall hate no man, but some you shall reprove, and for some shall you pray, and some you shall love more than your own life.
3 My child, flee from every evil man and from all like him. Be not proud, for pride leads to murder, nor jealous, nor contentious, nor passionate, for from all these murders are engendered. My child, be not lustful, for lust leads to fornication, nor a speaker of base words, nor a lifter up of the eyes, for from all these is adultery engendered. My child, regard not omens, for this leads to idolatry, neither be a diviner, nor an astrologer, nor a sorcerer, neither wish to see these things, for from them all is idolatry engendered.
My child, be not a liar, for lying leads to theft, nor a lover of money, nor vain-glorious, for from all these things are thefts engendered. My child, be not a grumbler, for this leads to blasphemy, nor stubborn, nor a thinker of evil, for from all these are blasphemies engendered, but be you meek, for the meek shall inherit the earth. Be you long-suffering, and merciful and guileless, and quiet, and good, and ever-fearing the words which you have heard. You shall not exalt yourself, nor let your soul be presumptuous. Your soul shall not consort with the lofty, but you shall walk with righteous and humble men. Receive whatever befalls you as good, knowing that nothing happens without God.
4 My child, you shall remember, day and night, him who speaks the word of God to you, and you shall honour him as the Lord, for where the Lord's teaching is spoken of, there is the Lord present. And you shall seek daily the presence of the Saints, that you may find rest in their words. You shall not desire schism, but shall reconcile those that contend. You shall give righteous judgment, you shall favour no man's person in reproving transgression.
You shall not be of two minds whether a thing shall be or not. Be not one who stretches out his hands to receive, but shuts them when it comes to giving. Of whatever you have gained, by your hands you shall give a ransom for your sins. You shall not hesitate to give, nor shall you grumble when you give, for you shall know who is the good Repayer of wages. You shall not turn away the needy, but shall share everything with your brother, and shall not say that it is your own, for if you are partakers in the imperishable, how much more in the things which perish?
You shall not withhold your guiding hand from your son or from your daughter, but you shall teach them the fear of God from their youth up. You shall not command in your bitterness your slave or your handmaid, who hope in the same God, lest they cease to fear the God who is over you both, for He comes not to call men with respect of persons, but those whom the Spirit has prepared. But do you who are slaves be subject to your masters, as to figures after God’s prototype, in reverence and fear. You shall hate all hypocrisy, and everything that is not pleasing to the Lord. You shall not forsake the commandments of the Lord, but you shall keep what you received, adding nothing to it and taking nothing away. In the church you shall confess your transgressions, and you shall not offer up your prayer with an evil conscience. This is the Way of Life.
5 But the Way of Death is this: First, it is wicked and accursed, full of murders, adulteries, lusts, fornications, thefts, idolatries, magic, sorcery, robberies, false witness, hypocrisies, a double heart, fraud, pride, malice, stubbornness, covetousness, foul speech, jealousy, impudence, haughtiness, boastfulness. Persecutors of the good, haters of truth, lovers of lies, knowing not the reward of righteousness, not cleaving to the good nor to righteous judgment, spending wakeful nights not for good but for wickedness, from whom meekness and patience is far, lovers of vanity, following after reward, unmerciful to the poor, not labouring for him who is oppressed with toil, ignorant of Him who made them, murderers of children, corrupters of God's handiwork, turning away the needy, oppressing the distressed, advocates of the rich, unjust judges of the poor, all-sinful. May you be delivered, my children, from all these.
6 See that no man makes you err from this Way of the Teaching, for they teach you without God. For if you can bear the whole yoke of the Lord, you will be perfect, but if you cannot, do what you can.
