Q. 84. What is forbidden in the ninth commandment?
A. The ninth commandment forbids whatsoever is prejudicial to truth, or injurious to our own, or our neighbor’s good name.
Therefore, having put away falsehood, let each one of you speak the truth with his neighbor, for we are members one of another. Ephesians 4:25
who does not slander with his tongue
and does no evil to his neighbor,
nor takes up a reproach against his friend;
We take this course so that no one should blame us about this generous gift that is being administered by us, for we aim at what is honorable not only in the Lord’s sight but also in the sight of man. 2 Corinthians 8:20-21
