Thanks for that LT. Are you saying then that it is possible to become a Christian without understanding the Trinity Doctrine? I am sure that you will agree that in order to believe this Doctrine it is necessary to understand it?
I am sure that you will also agree that, even in its simplest form as described here by Undisfellowshipped, it is extremely complicated and will be beyond the understanding of many people who would nevertheless like that "living relationship" that you mention.
