Those who say they are Christian and are sexually active outside the bond of marriage are as demons that must be cast out of church communities swiftly and publicly shamed.
1 Corinthians 5:11, 13
But now I have written unto you that you not keep company or associate with any man that is called a brother, who claims to be a Christian, but be sexually immoral or covetous, or an idolater or slanderer, a drunkard or an extortioner. Do not even eat with such people.
Cast the evil person from among you, writes St. Paul.
For as is written later in the same letter, You cannot drink the cup of the Lord and the cup of demons. You cannot partake of the table of the Lord and the table of demons.
