Matthew 10:33-35

But all who stand before others and say they do not believe in me, I will say before my Father in heaven that they do not belong to me. “Don’t think that I came to bring peace to the earth. I did not come to bring peace, but a sword. I have come so that ‘a son will be against his father, a daughter will be against her mother, a daughter-in-law will be against her mother-in-law.
