The Church must never compromise and accept sinful behavior as righteous. If we do, then we have lost our way and no longer serve God.
Only by abiding in the Word of God will you learn the truth. Jesus said that it is the truth that will set you free from the bondage of sin.
For unless you believe that I am He, you will die in your sins. That is the exclusivity claim for Salvation that is made by the Lord Jesus Christ.
Jesus is the Light of the World. Those who follow Him will never walk in darkness.
