So does the Bible:
Galatians 5:12
Thank you for leading us to Galatians 5:12. It is prophetic for our times.
Galatians 5
7 Ye did run well; who did hinder you that ye should not obey the truth?
8 This persuasion cometh not of him that calleth you.
9 A little leaven leaveneth the whole lump.
10 I have confidence in you through the Lord, that ye will be none otherwise minded: but he that troubleth you shall bear his judgment, whosoever he be.
11 And I, brethren, if I yet preach circumcision, why do I yet suffer persecution? then is the offence of the cross ceased.
12 I would they were even cut off which trouble you.
It should be clear that is metaphor based on verse 9. See verse 11, speaking of circumcision. You may recall that entails cutting, so it makes sense that he’s speaking there of cutting off from the body of Christ, which is the church - not by execution but by withdrawing from them.
Same chapter, speaking of murders -
21 Envyings, murders, drunkenness, revellings, and such like: of the which I tell you before, as I have also told you in time past, that they which do such things shall not inherit the kingdom of God.
Regretfully, I see no biblical authority for what you forcefully advocate.
