It seemed good to the Holy Spirit and to us not to burden you with anything beyond the following requirements: You are to abstain from food sacrificed to idols, from blood, from the meat of strangled animals and from sexual immorality. You will do well to avoid these things. Acts 15:28-29

Expel the Immoral Brother!
I have written you in my letter not to associate with sexually immoral people— not at all meaning the people of this world who are immoral, or the greedy and swindlers, or idolaters. In that case you would have to leave this world. But now I am writing you that you must not associate with anyone who calls himself a brother but is sexually immoral or greedy, an idolater or a slanderer, a drunkard or a swindler. With such a man do not even eat.
What business is it of mine to judge those outside the church? Are you not to judge those inside God will judge those outside. “Expel the wicked man from among you.”

Do not suppose that I have come to bring peace to the earth. I did not come to bring peace, but a sword. For I have come to turn
a man against his father,
a daughter against her mother,
a daughter-in-law against her mother-in-law—
a man’s enemies will be the members of his own household.
