My fiance is pretty violently opposed to religion (he's been burned in the past and has also had major surgeries that make him opposed to the idea of a god) and wants to make sure that there is nothing at the wedding that will trigger him. I want him to be happy and not upset on our wedding day and I am rather ambivalent about religion so this is fine with me. Is there a polite way of asking people to refrain from giving religious words of encouragement (i.e. God has truly blessed you) or openly wearing religious symbols? We also have people from multiple religions attending so we don't want it to be a big issue.
