Chapter 19 pretty much tells how to live like a Christian. I really like how Barnabus condemns abortion, since always thought it was murder. I think the whole abortion issue is settled thanks to Barnabus.
Chapter 19. The way of light
The way of light, then, is as follows. If any one desires to travel to the appointed place, he must be
zealous in his works. The
knowledge, therefore, which is given to us for the purpose of walking in this way, is the following. You shall
love Him that created you: you shall glorify Him that redeemed you from death. You shall be simple in heart, and rich in spirit. You shall not join yourself to those who walk in the way of death. You shall
hate doing what is unpleasing to God: you shall
hate all hypocrisy. You shall not forsake the commandments of the Lord. You shall not exalt yourself, but shall be of a lowly mind. You shall not take
glory to yourself. You shall not take
evil counsel against your neighbour. You shall not allow over-boldness to enter into your
soul. You shall not commit fornication: you shall not commit
adultery: you shall not be a corrupter of youth. You shall not let the word of God issue from your lips with any kind of impurity. You shall not accept
persons when you reprove any one for transgression. You shall be meek: you shall be peaceable. You shall tremble at the words which you hear. You shall not be mindful of
evil against your brother. You shall not be of doubtful mind
James 1:8 as to whether a thing shall be or not. You shall not take the name of the Lord in vain. You shall
love your neighbour more than your own
soul. You shall not slay the child by procuring
abortion; nor, again, shall you destroy it after it is born. You shall not withdraw your hand from your son, or from your daughter, but from their infancy you shall teach them the
fear of the Lord. You shall not
covet what is your neighbour's, nor shall you be avaricious. You shall not be joined in
soul with the
haughty, but you shall be reckoned with the righteous and lowly. Receive as
good things the trials which come upon you. You shall not be of double mind or of double tongue, for a double tongue is a snare of death. You shall be subject to the Lord, and to [other] masters as the image of
God, with modesty and
fear. You shall not issue orders with bitterness to your maidservant or your man-servant, who trust in the same [God ], lest you should not reverence that God who is above both; for He came to call men not according to their outward appearance,
Ephesians 6:9 but according as the Spirit had prepared them.
Romans 8:29-30 You shall communicate in all things with your neighbour; you shall not call things your own; for if you are partakers in common of things which are incorruptible, how much more [should you be] of those things which are corruptible! You shall not be hasty with your tongue, for the mouth is a snare of death. As far as possible, you shall be pure in your
soul. Do not be ready to stretch forth your hands to take, while you contract them to give. You shall
love, as the apple of your eye, every one that speaks to you the word of the Lord. You shall remember the day of judgment, night and day. You shall seek out every day the faces of the
saints, either by word examining them, and going to exhort them, and meditating how to save a
soul by the word, or by your hands you shall labour for the redemption of your
sins. You shall not hesitate to give, nor murmur when you give. Give to every one that asks you, and you shall
know who is the good Recompenser of the reward. You shall preserve what you have received [in charge], neither adding to it nor taking from it. To the last you shall
hate the
wicked [one]. You shall judge righteously. You shall not make a
schism, but you shall pacify those that contend by bringing them together. You shall confess your
sins. You shall not go to
prayer with an
evil conscience. This is the way of light.
