I wasn't trying to "win" in the way you think I was yet. I was just trying to gather information.
My default assumption when someone claims to be saved is that they are until proven otherwise, but believing that the Church and not Christ is the source of salvation is a convincing proof otherwise from my perspective. But then my mind goes into "rebuke" mode and not "plant some seeds" mode, because people who consider themselves part of the Church should be open to rebuke (though of course I still try to be kind about it, that doesn't come across easily over the net.)
For the sake of the rebuke, I wanted to understand what exactly they believe in so I could address it more directly, but that clearly wasn't going anywhere. By their logic, I didn't even have the right to ask because I'm not already part of whatever "Church" they're a part of. Between their aggression and the fact that I've never heard of a belief system that lines up with what they were saying, I saw trolling as a likely possibility, moreso than I let on at this point. I suppose I could have tried for a little longer before bringing it up, but as you can see, I only asked, and then stated immediately afterwards that I didn't want to assume ill intent.
So it wasn't intended so much an accusation as a test of the waters, but I suppose it didn't come off that way, and a troll wouldn't answer that honestly, so the only purpose it served was to protect my own pride against the vision I had of someone laughing at their screen going "look how long I'm keeping this fool in an argument, and they don't even suspect I'm trolling." I'll try to do better about that in the future.
As for the use of "preposterous," I did add "to me" to soften it a bit, and this is clearly someone who's able to handle that level of bluntness.
Thanks for your thoughts. I guess upon becoming sure that they were a troll, instead of calling them out to end it there, I should have shifted out of rebuking mode (since someone who's pretending to be a Christian for trolling purposes is not going to be open to Christian rebuke,) and considered whether I was in a position to share my faith. In this case, I think I was, but it might be too late now. I'll take another look tomorrow to see.
I think we're in agreement here. God gives us chances to bear fruit, but throws out the branches that don't. Predestination, as Calvinism describes it, says that He decides in advance whether they're going to bear fruit, and those He wants to bear fruit do, and those He doesn't never get the chance. I do not see that lining up with the idea that God is all-loving.
That being said, the Bible does say that nobody can come to Christ without God's call, so I can see how that could be seen as predestination, but there have been those who felt the call and turned away, some of whom came around later. I think in some manner, it might be a warning that you can't just decide "I'll get saved when it's more convenient for me," because God doesn't call at your convenience.
