How can they?
Because they “interpret” the Bible in the same way they “interpret” the Constitution—neither of which has anything to do with the way the original documents were written.
Wrong on both counts.
Some claim to be Catholic when in fact they aren’t. Some claim to be Christian when they aren’t really. Some claim to be Jewish when they aren’t, in that they don’t follow the Bible. Some claim to be Greek/Eastern Orthodox when they aren’t in that they don’t live the teachings.
How can any Lutheran, Presbyterian, Baptist, Southern Baptist, COE, Episcipalian, Assembly of God, Pentecostal, etc. vote for someone like Obama? I don’t know but there are plenty who claim they are yet they will vote for Obama.
