The Gospel According To Luke
-- 12:51-2 "Suppose ye that I am come to give peace on earth? I tell you, Nay; but rather division: For from henceforth there shall be five in one house divided, three against two, and two against three."
-- 14:26 "If any man come unto me, and hate not his father, and mother, and wife, and children, and brethren, and sisters, yea, and his own life also, he cannot be my disciple."
-- 19:27 "But those mine enemies which would not that I should reign over them, bring hither, and slay them before me."
The Gospel According To Matthew
-- 10:34 "Think not that I am come to send peace on earth: I come not to send peace, but a sword."
-- 10:35-6 "For I am come to set a man at variance against his father, and the daughter against her mother, and the daughter in law against her mother in law. And a man's foes shall be they of his own household."
-- 15:4 Jesus reiterates the commandment to kill children for cursing their parents: "For God commanded, saying, Honor thy father and mother: and, He that curseth father or mother, let him die the death. But ye say,... [snip] ... Thus have ye made the commandment of God of none effect by your tradition." (Jesus, reinforcing God's commandment from Exodus 21:17, Leviticus 20:9, and particularly Deuteronomy 21:18-21, which detail the requirement that parents bring stubborn boys to the city gates to be executed by stoning. Here, Jesus criticizes the humanitarian efforts of the Pharisees, who struggled for centuries to find ways to soften the impact of this brutal commandment, and to make it virtually unenforceable.)
The Gospel According To John
-- 15:6 "If a man abide not in me, he is cast forth as a branch, and is withered; and men gather them, and cast them into the fire, and they are burned." (This passage, a quote from Jesus, was used for centuries to justify burning our predecessors at the stake for refusing to believe.)
