You need to explain yourself more. No one can help you unless they understand what you mean. You need help with chords. Then you write out some left hand two note chords(diads).And you write some three note upper structures (triads) that go with your diads. These harmonic structures might sound good. Then again they might sound bad. What does your intuition tell you? Remember this. There are a lot of people in the congregation who know what good church music should sound like. Even though, they themselves may not be able to play or sing anything.You should use your intuition. If it sounds right, it is right. If it sounds wrong, it is wrong.
