Depends on the design of the church I imagine…ours its three lines, two abreast up the aisles, priest at center line, LEM’s at the other two. Most recieve it in the left hand, put it on their tongue with the right, then step off to another LEM with the Chalice for the Blood. A few take it on their tongues directly. My wife, an Episcopalian goes up about once a month and keeps her hands folded across her chest for a blessing (as do many young children).
Tonight I was watching to see how many blessed themselves after recieving, it was actually only about three or four out of fifty or so…
It is interesting, every few weeks the primary priest explains this procedure for non-catholics and ‘apologizes’ for want of a better word that they cannot take the eucharist, and ads he looks forward to the day they might be able to do so. Probably not anytime soon I imagine. (Please - I’m not trying to start a debate, just mentioning how eucharist goes at my church!)
