This from the Uncomfortable In Church thread

"Christmas Eve - I have seen communion served in a church where there was only one Christmas Eve Service - filled with strangers - most were unused to the ritual of the church - they looked very uncomfortable. I think this leads me to start another thread." CrazyHeart

So what I am wondering is how much of ritual and music and readings and other things  should we give up to be welcoming to others who come to the church?
