Communervise?

INCLUDING HOLY COMMUNION

If this were on the sign out the front of a church, attached with the advertisement of a church service, then I don't think most people would be more inclined to attend.

Why?

Because, if I weren't a Christian, I would have little idea what the above sentence would exactly mean.

Maybe it's just the way I view things, but perhaps the church overestimates either a)the amount or accuracy which non-believers understand what happens during church services, or b) that everything we do is attractive to an outsider.
