My background is also academic, but I was taught that Protestants believed that people when people were born, it was already predetermined whether they went to heaven or hell.

As others have said above, that's true for some Protestant denominations. I grew up Missouri Synod Lutheran, which preached that it's all a matter of faith. If you have faith, you're saved -- nothing was decided at birth. Also, faith will motivate you to be a good person.

That is straight Calvin. Definitely not all Protestants believe that!

This elaborate wikipedia article says there are three main branches within Protestantism: Calvinist, Lutheran, and Arminian. [link]

I don't think we dealt with "new" religions in this course- It was Judiasm, Islam, Christianity (divided into Catholic and Protestant (as in the Protestant Reformation times)).

I'm not aware that any modern Protestants still believe that. It is definitely Calvinist/Puritan thought but not mainstream.

Thanks. It seems like it plays out in a few different ways. But I can see how it all seems to fit together. I guess it all starts with the idea of needing to be saved by belief.

Okay, and on the What Am I Getting Myself Into? front, the weather tells me that it will rain on Friday, ie, while we are on the boat and sailing home from Catalina. Oh dear. Guess it's good I don't mind the rain? Will be lots of kids thinking they want to keep dry in the hold, until they realize how queasy it gets down there.

Fred is my brother in Missouri Synodness.

We were also taught that we could lose our faith and thus end up in Hell if we died in that state.

Of course that brought all sorts of questions to my mind--like what if you just constantly switch between having faith and not having faith? You could rapidly alternate between being saved and not being saved.

And what if you have faith all your life, but, say, just before your death you're in such agony and so messed up psychologically you lose your faith seconds before you die? The whole thing seemed problematic to me. Plus the whole binary nature of faith/no faith seemed weird, because in real life I'm never 100% certain about anything. So if I had 60% faith but suddenly my faith dropped to below 50%--was that the cutoff point for eternal damnation?

It's possible I thought too much about this stuff.

Martin Luther is definitely all about salvation by faith, and I think not by predestination. Wasn't his whole thing anti-indulgence?

I thought the pre-destination was anti-indulgence too. Because if you were pre-destined, then you didn't need to buy indulgences!

If you have faith, you're saved -- nothing was decided at birth. Also, faith will motivate you to be a good person.

In my head I was separating the belief that once saved you can't be unsaved from predestination, and seeing the former as more along this line coupled with Steph's point about humans being prone to sin and needing grace even after they have been saved. But I see now that there's a bunch of different POVs out there.
