I know many people in the sciences who are religious. They use logic rigorously in their research. And there are Christian fellowships at every big name university famous for scientific research. This is a problem for atheists to explain, I think.
I know many people that go to church for their own gain. To be seen as a pillar of the community because they sit in church on Sundays. Politics if anything.
I even know a doctor that is a homosexual, but has a girlfriend that he takes to church every Sunday to be seen with a woman. They have no other relationship other than he picks her up Sunday mornings and goes to church. This poor girl cant understand why the dont move forward in the relationship. He drops her off and goes home to his "room mate" of 15 years."See you next Sunday".
