I recall R C Sproul blasting the ECT document (Evangelicals and Catholics Together) which made lame attempt to bring both together and for Evangelicals to name Catholics as brothers.
This document attempted to make a co-belligerency against the alternative lifestyle, abortion, other issues. Sproul said something like we are already standing against this, on both sides, but that does not make us brothers. It was something along those lines.
D James Kennedy also spoke up against it because it lamented attempts to evangelize Catholics, and Kennedy said something about him still evangelizing his own members in his own church, showing how absurd it is for them to worry about Catholics being evangelized.
Standing against abortion, that lifestyle, giving to charities doesn't a saved person make, nor does it mystically reveal they must be born again, looky at what they are doing.
