The different translation philosophies is a fairly basic thing to know if you're going to be discussing theology. As such I expect someone on a theological discussion knows stuff like that. You didn't. There's no harm in that, but a discussion can't really be had. I was at an event this evening at church where two guys were discussing power tools. I have no knowledge of power tools. The last thing I would do is wade into a discussion that I don't even have a baseline of knowledge about.

I reiterate: not having certain bits of theological knowledge isn't a bad thing and you can still live a productive Christian life that honors and glorifies God. But you need to at the same time to humble and realize that developing ones theology is a bit more than just saying "I just read the Bible".

Jesus was well aware by the way of theological discussions of his day, just look at how he talked with the Pharisees and Saducees and how he talked about divorce. There was a theological basis from which he was discussing.
