People are always talking about the first church. The real first church was that gaggle of people who followed Jesus around. We don't know anything about them. But he apparently didn't ask them what creed they subscribed to, or what their sexual preference was, or any of that. He fed them. He healed them. He forgave them. He is clear about sin, but he was also for forgiveness.
Especially among Christians in positions of wealth and power, the idea of reading the Gospels and keeping Jesus' commandments as stated therein has been replaced by a curious process of logic. According to this process, people first declare themselves to be followers of Christ, and then they assume that whatever they say or do merits the adjective "Christian".
It gets darker and darker and darker, and then Jesus is born.
