The Mar and Means of Unity

Phillippians 2:1-18, Heidelberg Catechism Lords Day 40.
WHAT IS GOD’S WILL FOR US IN THE SIXTH COMMANDMENT?
A. I am not to belittle, insult, hate, or kill my neighbor–not by my thoughts, my words, my look or gesture, and certainly not by actual deeds–and I am not to be party to this in others;(1) rather, I am to put away all desire for revenge.(2) I am not to harm or recklessly endanger myself either.(3) Prevention of murder is also why government is armed with the sword.(4)
