Fr. Z offers a catechetical note on receiving Communion on the tongue. The logistics can be a bit intimidating - especially when you have only ever been taught to receive on the hand.
I first received on the tongue when attending the beautiful St. Agnes Church in St. Paul, Minnesota. They did not have the EF Mass at the time I was there (summer of 2006) but the priests there offer the Ordinary Form of the Mass with extraordinary reverence. Masses are said ad orientem and all receive communion kneeling at the altar rail and on the tongue. It was a profoundly moving experience for me. When I kneel to receive, there is a great feeling of reverence and awe that washes over me. Not that I don't feel awed when receiving my Lord in my hand - but I think that posture emphasizes the sacred nature of that moment.
After seeing some people recieving on the tongue at the Basilica, I was emboldened to try it during Holy Week, when they had enough priests that no EMHCs were used and priests were distributing communion to all. Luckily I was able to make my wish to recieve on the tongue understood, and I think I prefer that way over receiving in that hand.
