As much as 75% - and this would also depend on the type of Church, there are many groups that meet, such as Joel Osteen, TD Jakes and others where you will get people like PaulScott who do not accept the Bible as the revealed truth. Again, I have more experience within the Church than you, you simply pick the worst examples you can, set them up as strawmen and knock them over, I could waste my time and do that as well with Darwinists, but what is the use ?
