Gay Marriage

I was reading in my newspaper today about local pastors standing outside the courthouse and protesting against gays getting married, reading Bible verses at them, and denouncing both those who went in to get married, as well as the government officials who were doing the marrying.

I'm a bit puzzled as to how this is part of the Great Commission, or preaching the gospel.

I'm wondering what Paul would think about it. Oh, I do know what Paul would think about it:

What business is it of mine to judge those outside the church? Are you not to judge those inside?

1 Corinthians 5:12

It also seems to me that Jesus' approach with sinners was somewhat different than how these Pharis--um, preachers--are operating. In fact, I seem to recall he saved his venom for people who were doing the sort of things these preachers were doing.
