When you factor in how Chaplains in both Congress and the military do not currently cater to non-religious people -- remember: atheists are currently banned from taking on the role -- and how the Senate Chaplain has almost always been a Bible-believing Christian (with the exception of a couple of Unitarians, both of whom were still believers), it's just another government benefit for Christians.
