Sorry, but I don’t accept your photo of Einstein as being a good example of how to reverently stick out your tongue to receive Holy Communion. I don’t know where you got the notion that he was demonstrating how to receive Communion on the tongue.
Whoa, calm down, it was in jest. I thought that would be obvious, as Einstein is well know for being Jewish, not even Christian.
I would honest prefer people to be a little more Einstein then many people now who open their mouth about a 1/2’’ and have their tongue at about their lips though.
Whether you were kidding or not, that is not how far one needs to stick out their tongue. If one opens their mouth wide and sticks their tongue out just over the bottom teeth to the bottom lip, that is perfect.
For COTT, the tongue needs to extend (for the tip) at least just past the lower lip (or at the very least the tongue is on top of your lower lip). That and opening your mouth wide enough will make it easy for the priest/minister to place the host on your tongue. Any less of an open mouth, and the host ends up dangling precariously half off of your tongue, or the priest/minister is competing in the weirdest precision competition on Earth as they attempt to get a host into a very small hold.
If you have your tongue wholly inside of your mouth (behind the lip) then we’re back to Communion in the Mouth, where the priest/minister is either putting their fingers in your mouth (and that’s just unsanitary) or dropping the host into your mouth (again, like a Carnival game). Again, it’s Communion On the Tongue. The host is suppose to be place
onto your tongue, and to do that the priest/minister needs to be able to see your tongue and be able to maneuver the host onto it.
Am I deliberately being a little over the top? Yes. But it’s just to show that doing the posture right is important. It’s not easy, nor does it come automatically to people and many do need instruction on how to do it right.
Here’s a video from Busted Halo (Fr. Dave Dwyer) I found on “How to Receive the Eucharist”. Notice the women receiving on the tongue at ~1:19,
that’s how it should be done.
Once at the Chapel on campus here, the priests actually went and did a little announcement on it at Daily Mass. The announcement basically came down to “Stick out your tongue”. Even at communion, the priest still had to say a few time to people while they were receiving “Tongue. Stick out your tongue”. That actually happened, I was there. None of this little story is an exaggeration.
I know I keep emphasizing the tongue, but it’s hard because I need to get around some cultural awkwardness in North America that has taught us how wrong it is to ever stick out your tongue. So, in conclusion, ignore what your mother said, and Stick. Out. Your. Tongue.
