Jensen craves attention. He got some by declaring himself an atheist and joining a (supposedly) Christian church, and then writing about it in a leftie rag for all his atheist buddies to guffaw about. The "pastor" of the church let him join for similar reasons.
Two more interesting questions are why would any Christians go to this church, and why would the presbetyrians put up with it.
The Methodist Church is eat up with non-Christians who like inflicting their liberalism on the congregation. I often hear people complain about Jesus being "narrow-minded" when He says He is the only way.
