It's been my experience over a half century of this Bible study thing that most people within Christianity have their mind made up already what they believe. Trouble is - most of them have really just gone with the overall package given to them by their own "group".
It has always seemed to me that folks who do that aren't really anymore "noble", as God says (Think Barean!), in their approach to investigation when they are coming from a orthodox position than one who is subscribing to the teachings of an out and out cult. Maybe they lucked out and ended up associated with a more correct group than the cultist - but it was more sheer luck (or providence) that got them there than any particular nobility.
As one who was an athiest before finding out that the Bible is God's word to us - I've always tried hard to listen to and investigate in the scriptures, any point of view from another group.
Most are rejected since I'm pretty well grounded by now. But occasionally I'll have my eyes opened to another view of things. As a result - I've ended up with a rather eclectic mix of Christianity while still remaining in the fold.
Occasionally I am informed by one group (Reformed for instance) that I can't be one of them since I don't subscribe to all 5 points of so called Calvinism or some other criteria. I've been questioned how I can still call myself conservative when I subscribe to some concepts from the "word of faith" crowd. Or -how can I call myself orthodox when I speak in tongues in my prayer life.
It seems to me, after 55 years of trying hard to listen to the Holy Spirit, that a true "Bible believing Christian" will end up with a real mix.
Well - enough rambling for now. I'll just say for now that as I get older, I have less and less patience with folks who start or participate in a doctrinal discussion only to beat their own drum and not to have an informative discussion.
That's the way it often is online. Comes with the territory I guess.
