On this we agree completely. It doesn't matter if the Church that satan claims membership in is Catholic or Protestant. No organization truly dedicating itself and its works to Jesus condones or authors evil. That doesn't mean there are not wolves in sheep's clothing within any of them.
The wolves are generally the first ones in the door! And we know the enemy of mens souls trods within them as well. Were this not so neither Protestant, Evangelical, Catholic or any other denominations would be contending with the vast infilitration of evil we see in the church family today. I do not see Obama as a Christian...no matter where he claims his affiliation..."the fruit" is not there, other wise is clearly seen. BTW didn't even Hitler claim to be a Christian? I think so.
