1) James is not contradictory with Paul....if read in context. You need to understand who the audiences are to which James and Paul are writing.
2) I am not aware of any contradictions in Paul's writings. Again, you have to keep it in context. That may be where your concern is originating.
3) If you're really concerned with an accurate translation, get a copy of the Bible either in the original Greek, or use an interlinear or use the NASB translation.
4) I am not aware of anyone who worships the Bible. The Bible is the Word of God so we should study it to learn from it what God's will is.
5) Suggest you read up on the OT and NT canon formation. I would recommend a book by F.F. Bruce, The Canon of Scripture.
I hope this helps somewhat.
Thanks. Well advanced . I am open minded. I will consider. GB!!
