sin is not a proper response to other people's sin

Homosexuality is sin; so too is murder, as is wishing for people to murdering oneself.

The gospels tell of a time when some people brought a woman caught in sexual sin to Jesus. Jesus said that the one who had no sin should be the first to throw a stone at her. Jesus was the only one present who had no sin, and He did not throw a stone.

Jesus did not excuse her sin; He even told her to not commit that sin again. Yet His words also sent away her accusers.

We do not properly respond to other people's sins by falling into sin ourselves. Two sins we can fall into are the extremes of either permitting and supporting the other's sins or the opposite extreme of hating the people and wanting to harm or even kill them.

The bullying tough-guy act should have no place in churches. It is no more than a perverse caricature of what Christian faithfulness should be. Similarly, the compromising nice guy act also has no place in churches. It is no more than a perverse caricature of what Christian love should be.

Jesus did not do what the accusers wanted Him to do, He did not condemn the sinner, but He didn't approve of her sin, either. I suppose that is a difficult position to put ourselves in, and open to misinterpretation, but that is the place the church needs most to be; to not be either the self-righteous accusers or the equally self-righteous approvers, but to be compassionate to people who are sinners like ourselves and who may even be suffering for those sinful acts.
