He's right. In fact I have him on record saying that being Catholic does not exclude one from being a Christian.
In that case, I retract my statement about e-s claiming that Catholics are not Christians. However, the issue is not whether any ONE Catholic is a Christian; it is whether Catholicism confers Christianity on all faithful adherents. I don’t think we have his statement on that point.
We do have the BD statement, though, and that’s a good one!
