You cannot really properly understand the New Testament without getting to grips with the Old Testament, and visa versa. Anyway the OP wasn't talking about backwoods Presbyterians who are very interested in the OT but feel good "health and wealth" "Mega-Church" types who tend to ignore it as much as most Irish Catholics. The more I think about it the more I understand that the nearly all of the problems in contemporary Irish Catholicism come from ignoring the Old Testament.A lot of the bible protestants seem more interested in the Old Testament than the words of Christ. I dislike the use of the word fundamentalist to describe them. My opinion is that a fundamentalist christian would be a member of an isolated eastern church which had not agreed to the teachings of the early councils, the teaching of Christ as recorded in the gospels is quite simple.
