Shun Vulgarity in Every Form
Fathers and mothers, husbands and wives, brothers and sisters, do not educate yourselves in the line of vulgarity of action, word, or thought. Coarse sayings, low jests, lack of politeness and true courtesy in the home life, will become as second nature to you and will unfit you for the society of those who are becoming sanctified through the truth. The home is too sacred a place to be polluted by vulgarity, sensuality, recrimination, and scandal. Silence the evil word; put away the unholy thought, for the True Witness weighs every word, sets a value on every action, and declares, “I know thy works.” Low, cheap, common talk should find no place in the family. When the heart is pure, rich treasures of wisdom will flow forth. Indulge in no foolish talking in your house. Even very young children will be benefited by “the form of sound words.” But idle and foolish words exchanged between father and mother will lead to the same kind of words among the children; while right, candid, truthful, and serious words will lead to the same in all the household and will lead to right actions also.

1 Peter 3:10-12 KJV
10 For he that will love life, and see good days, let him refrain his tongue from evil, and his lips that they speak no guile:
11 Let him eschew evil, and do good; let him seek peace, and ensue it.
12 For the eyes of the Lord are over the righteous, and his ears are open unto their prayers: but the face of the Lord is against them that do evil.
