get real, you have raised an excellent question. beating down RCC while the tents of Sodom surround our churches....slamming catholics isn't going to deal with what's at the doorstep.
judgment starts with the household of God.
we won't tend to our own gardens.
wurmbrand spoke in his books of the orthodox losing their trinkets in the prisons and growing in their relationship with God, but his efforts were to deal with the direct issue at hand, the communist take over of his country, he stood at the meeting and spoke of Christ being the head of the Church, not marx's mercenaries.
if a church is teaching that revelations is about pretrib rapture or RCC, they are not counting the cost. I'm the first to share the gospel with someone who's catholic, that's not the point.... its the closing up of the book of revelations for this generation. so you kick out RCC, you've got a million other antichrist philosophies to deal with, its been 400 years, time to deal with the secular humanist church that runs our day, instead of being chummy with it.
even satan knows how to quote scripture.
