Hello.I can help you, because I was/am in the same dilemma.I just would request you bare with me in my answers.As I have spoken with all kinds on these forums,chat rooms etc and they find my approach too much to bear.So they become bitter, resentful etc. It's as the Christ stated, his 'truth is like a 2-edged sword' , it  cuts into the deepest depths of the soul.

I became a Christian and followed the norm.I flowed with whatever was taught me, because I thought ,'well,those guys are of GOD',and they claimed this continually. Often stating who was 'I to question them,the Authority of GOD himself? 'You're a 'babe' in Christ, you don't know anything.Until we (the Church leaders,powers) say you're mature.Until then don't even think about questioning our authority.'

I am continually told that the mystery of God is too much for me to understand.True to a point.But if the spirit speaks through you,doesn't he reveal the mysteries of God so you'll understand?At least a little?

I was passionate,driven so I decided I'd pray and ask the Holy Spirit to remove the veil from my eyes, and show me the truth.Well,I believe he did/has.Because upon meeting the Jehovah Witnesses,whom I don't have a regular affiliation, they merely were door knocking,they helped me hunger even more for Gods truth.So I dug deeper.And found many religious factions still cling to the pagan customs of Xmas belief as the time Jesus was born,and many other traditions,while cussing pagan practices.The sabbath is ignored,the trinity fallacy is believed and contradicted as often as it's mentioned.So I actually began to read the Bible from the beginning and found many contradicitions between the Old Testament & the New.I have found an interesting fact, that I don't think any Christian will know, or accept,even though it is fact!

It's a good thing that those 3 are the cornerstones of your belief. What you need to do is pray that God opens your ears and eyes to the Truth. One famous thing that Jesus said in the Bible was, "I am the Way, the Truth and the Life. Nobody can come to the Father, except through me." Many people stand with you on that first question you had. I'm not a fundamentalist either, and I have NEVER been to a Catholic church service, as my father brought us up in a Pentecostal church. Now I go to a different local church with my older sister. I used to question these things as well, but when I asked my youth pastor, he told me to have a quiet time with God every day, even if it's just 5 or 10 minutes. I started with 20 minutes and now I soak in the Word for almost 3 hours a day. I hope this has given you an answer.
