I don't claim to know the true intentions of this church and I don't claim to never act foolishly myself, but the folly of this action makes me very, very sad. If our purpose is to advance the kingdom of God then we would be wise to show love to the world around us and not stir up pointless trouble. The truth is offensive enough in itself without our help.
"You have heard that it was said, 'Love your neighbor and hate your enemy.' But I tell you: Love your enemies and pray for those who persecute you, that you may be sons of your Father in heaven. He causes his sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous. If you love those who love you, what reward will you get? Are not even the tax collectors doing that? And if you greet only your brothers, what are you doing more than others? Do not even pagans do that? Be perfect, therefore, as your heavenly Father is perfect." Matthew 5:43-48
We have to earn the right to be heard, and this is really not doing the trick. In all things we have to remember that "God demonstrates His own love for us in this: while we were still sinners, Christ died for us." Romans 5:8
