We are living in a time when the Bible is being reinterpreted to mean things it never meant. One of the primary rules of interpreting any ancient document(s) is that it cannot mean something it never meant. That would be putting words into the mouths (pens) of those writers.
When Jesus said the two greatest commandments were to love God with all of our heart, soul, mind and strength and our neighbor as ourselves, He did not mean to accept and condone any and every lifestyle as normal. If that is what He meant, why did He tell the woman caught in the act of adultery to go and leave her life of sin? And IF that was what Jesus meant, why did Paul speak so harshly to the church in Corinth for having accepted a man who was committing fornication (sex outside of the marriage of one man and one woman) with his step-mother?
In 1 Cor. 5:1ff he wrote, “It is actually reported that there is sexual immorality among you, and of a kind that is not tolerated even among pagans, for a man has his father’s wife. And you are arrogant! Ought you not rather to mourn? Let him who has done this be removed from among you.” He went on to say that such discipline and the refusal to associate with sexually immoral people was intended for people who call themselves Christians and live that way. He said he was not meaning to refuse to associate with people of the world who live that way. He was talking about discipline of Christians who live UNREPENTANT in that lifestyle. He went on to say, “Purge the evil person from among you.”
If they repent, of course we are to embrace them and pray with them and encourage them. But if we embrace them while they are continuing in that behavior, they will probably not sense a need for repentance.
We need to reject the modern definition of “love” as meaning “absolute acceptance of any and all behaviors/lifestyles”. God loves us and disciplines us and confronts us. We need to love each other enough to discipline and confront IF we see one another living in unrepentant sin. The goal of it all should be restoration. It is not loving to allow one another to continue in sin.
