Answer:
Step-by-step explanation:
I don't think they are in conflict. Not when you talk about behavior which people really tend to ignore when they get into this quagmire the question represents.
I have a degree in physics, and I go to church at least twice a week if I can make it. Sometimes my health gives me problems.
Worse yet in the spirit of the question, I study with the Jehovah's Witnesses. So you might think that disqualifies me. I'm going to offer you something anyway.
So let's start with behavior. The old Testament is composed among other things of 613 laws that must be obeyed. Of course no one can do it. But there are certain fundamental laws that can be stated and those can be followed without question. Or we can try to follow them.
The first 4 talk about how we are to treat God. The second 6 deal with how we ought to behave. In our behavior, these 10 laws represent the axioms of religious law in the old Testament. Notice I used the word axioms. That's the same word the Greeks used when they enunciated their geometric findings. These principles (there are only 5) can only be accepted. They cannot be proved. Sound familiar? It should.
I have only presented you with these few thoughts because the question you ask leads all over the map. People who reject truth no matter what the source are defiling what is best in humanity. Try to accept what each branch of knowledge does.
It looks like I really didn't offer you any answer to what you are after. I choose not to. It's a biased question and I think the answer goes much deeper than slinging mud from one side by the other. I think we must coexist as best we can listening to the strengths we find wherever we look. Anything else leads to hatred, and that is never something I will do.
