I personally am not worried about the sermon, i can sit there and listen or simply meditate or silently chant to myself. The problem comes with prayer at first I let my ego arise and say "NO!" now that i think about it maybe i should take a stand for the benefit of all people there.
My plan is to join in prayer holding hands so no one gets offended. Making sure i avoid any suffering i can cause in another person. In the prayer i can do 'silent illumination' or chant Om mani padme hum' silently. I am still a bit off on this, I wanted to share with you guys to see what advice you can give me or at least your take on it.



I agree with this. You could think along these lines - these people, just like every other being, simply want to be free of suffering. If the thought of praying to "God" or Jesus makes you uncomfortable, just bear in mind that to these people, God and Jesus simply represent the means to end their suffering. As long as they're not praying for harm to others. . . I don't see that you could go wrong.

If you aim to be kind, then everything falls in line with your principles. Getting hung up on form may or may not be relevant, only you can decide what is or isn't important to take a stand on. Glad you figured out what worked!
