…not be a fundamentalist.
Short answer Yes.
Long answer YES! In fact I would beg to argue that fundamentalism is such a stretch of the Gospel that it leads to heresy. I make no apologies here but my intent is not to offend. Here is the thing. The Jews thought that they had to keep all these laws and it would bring them closer to understanding God; make them more holy.
This is where Paul (and you can read it for yourself in Galatians, Hebrews, etc.) comes in and says, hold on a second. You have become slaves to the law. You have let the law, not bring you closer to God but have let it pull you so far away from God that you are leading others…others who think the law is the way…to become slaves to the law as well.
As (a) Christian(s) I(we) need to be careful of how many things we want to put between us and our relationship with Christ. Listen, God can tear down walls, but why build them in the first place?
