The Google agrees...83% of US citizens define themselves as Christians. I was kind of surprised it was that high of a percentage. Alas, according to a google search, a much lower percentage, around 40%, attends church on a regular basis. That number does comport with my experience among my coworkers and friends.
Well, I am one who comports with the idea that one need not attend a mortgaged building , sit like a stone for an hour to receive weekly absolution listening to some “professional” Christian doing public prayer in violation of the commands of Jesus and lying about the tithe to fatten his 401k and pay his home mortgage. A Christian accepts Jesus as the Son of God— That is all that is needed for ever lasting life. John 3:16-18
