I hope you get two other opinions, at least, before you believe this pastor knows Calvinism and calls its doctrine a Trojan Horse. I already see him deliberately twisting some of the Calvinistic meanings concerning their T.U.L.I.P. based on my little experience of this doctrine. I am not a member or follower of any denomination and including many doctrines, including Calvinism. And I do believe that in the main, most of the Calvinistic thinking is scriptural indeed. And it is based on what I believe they mean, their understanding of what they claim. I will also say that there are only a true handful that actually know what Calvinists really mean by their T.U.L.I.P. I surely do not know the intend and all their meanings in their doctrine, so I'm not quick to judge, and especially based on another pastor's word, out-of-hand.
This pastor is like a Trojan Horse in my opinion. I would revisit this clip again and ask questions along the way about why he forces only one meaning on his audience for all the key Calvinistic key concepts. Context is short in this clip, done intentionally. He definitely wants his audience to be steered to his own created one-sided debate and discussion. I would challenge him on his understanding in several places of his discussion.
For example for (T) Total Depravation - he says that no human born is spiritually inclined to know God or look for him (all my words like his), and I agree and so do Calvinists, and most believers in Christ.
Then he says Calvinists believe that God regenerated or makes them alive to know him. And I also agree with this idea with reservations. Now the poison he adds in, is this, he deliberately twists the word 'regeneration' to quickly mean 'being saved' with the spirit of Christ. To me, making someone alive to even know God is scriptural and it does not mean being reborn at that time. It's like turning on the light to even see spiritually. I believe or want to believe that Calvinists are not saying that that person is now reborn spiritually at this point.
We have had this discussion of Calvinism many times on this forum/site, and yet I believe I have not known anyone to know the entire doctrine correctly, or there is no one who is an expert on the subject; either arguing for or against this doctrine or otherwise. That's the problem. It's like calling something a threat when everyone speaks as if they know what it is and yet nobody really knows what it is when we get down to it. Just plain old gossip and idle talk, including this video clip.
