What Does The Bible Say About Politeness?
Quotes are from the RSV Catholic Edition or the Douay-Rheims
Proverbs 18:24 – A man amiable in society, shall be more friendly than a brother.
Ecclesiasticus 4:7 – Make thyself affable to the congregation of the poor, and humble thy soul to the ancient, and bow thy head to a great man.
Ecclesiasticus 31: 12-21 – Art thou set at a great table? be not the first to open thy mouth upon it. Say not: There are many things which are upon it. Remember that a wicked eye is evil. What is created more wicked than an eye? therefore shall it weep over all the face when it shall see. Stretch not out thy hand first, lest being disgraced with envy thou be put to confusion. Be not hasty in a feast. Judge of the disposition of thy neighbour by thyself. Use as a frugal man the things that are set before thee: lest if thou eatest much, thou be hated. Leave off first, for manners’ sake: and exceed not, lest thou offend. And if thou sittest among many, reach not thy hand out first of all: and be not the first to ask for drink.
Ecclesiasticus 41: 19, 24-25 – Wherefore have a shame of these things I am now going to speak of. […] Of theft, and of the truth of God, and the covenant: of leaning with thy elbow over meat, and of deceit in giving and taking: Of silence before them that salute thee: of looking upon a harlot: and of turning away thy face from thy kinsman. Turn not away thy face from thy neighbour, and of taking away a portion and not restoring.
