You can't help him unless he wants your help. I suggest that your focus on helping is adding to his reasons to be angry. Helping comes across as I know better than you or even I'm better than you, I know more than you. It definitely gives the message that you're unhappy with him but not in a direct way. Helping can be passive-aggressive.
Be direct with him. Tell him how his anger makes you feel. Use I statements. Tell him you've tried to help and it's not worked and so you're going to stop.Tell him you're going to take care of yourself and then do it.
Do not stay in the room when he yells at you. Tell him you won't tolerate being mistreated and if he wants this marriage to work the two of you will have to try doing something about it.
I strongly urge you to talk with your pastor if he's also trained as a counselor. You need some help in learning how to deal with your husband's anger. You do not have to take it. You can live in the same house and defend against his anger to the point that he'll learn a different way of dealing with his feelings or you leave.
I also suggest you read Non-violent Communication. They have a web site and a book that I know of. It teaches how to talk so that the other person doesn't feel judged. How to express your feelings in a way that's more likely to get a positive reaction. It's an excellent course in communication skills.
