Heidelberg Catechism: ' What is required in the ninth commandment?'
LORD’S DAY 43
112. What is required in the ninth commandment?That I bear false witness against no one; twist no one’s words; not gossip or slanderer; join in condemning no one unheard and rashly;1 but that I avoid, on penalty of God’s heavy wrath,2 all lying and deceit, as being the proper works of the devil; in matters of judgment and justice and in all other affairs love, honestly speak and confess the truth;3 and, so far as I can, defend and promote my neighbor’s good name.4
