“Contention is directly against that which is the very sum of all that is essential and distinguishing in true Christianity, even a spirit of love and peace. No wonder, therefore, that Christianity cannot flourish in a time of strife and contention among its professors. No wonder that religion and contention cannot live together.” Jonathan Edwards, Charity and Its Fruits
Strife is among the sins Paul lists as evidence of a mind disapproved by God and incapable of reasoning according to God’s standards (Romans 1:29). Galatians 5:20 says that those who practice it (i.e., whose life is characterized by it) will not inherit the kingdom of God.
