Chapter 26 — Part III — The Ten Commandments

Section 581. Q. Are there not still some more subtle forms of murder? A. To this sin are more or less referable all acts and words against charity; all which unjustly affect the peace and security of our neighbor; and, lastly, all inward malice against him, even though it be not shown openly. Whosoever hateth his brother is a murderer. 1 John iii. 15.
