As far as opinion goes, it does not matter what I think as to whether you should receive communion on the tongue or in the hand. According to the General Instruction of the Roman Missal (paragraph 92) you have the right to receive on the tongue as a universal rule. You may receive in the hand where the conference of bishops with papal approval has deemed it permissible. (It is interesting to note however that the rest of the short paragraph warns against possible difficulties with receiving in the hand and actually forbids the practice if there is a risk of profanation.)
The risk of abuses when communion is received in the hand increases dramatically and it is incumbent upon the communicant to put forth the extra effort this privilege demands in order to make sure that the Blessed Sacrament is afforded all of the attention and care of which He is deserving. It is also vitally important that pastors make sure that his people are properly disposed to receiving in the hand if they so desire it. To that end, here are a couple of notes:
If you are not able to properly receive in the hand; don't. If you have a hand in a cast, if you are on crutches, if you have a hymnal in your hands, if you have your hymnal (or purse or any object) shoved up under your arm (no matter powerful your armpits are), if you are carrying a baby, or holding hands or need a hand to balance yourself or for any reason you do not have full and free use of your both of your hands and arms for the reception of the Blessed Sacrament, receive on the tongue.
So suppose your hands and arms are not otherwise occupied or disabled, please consider the following.
This is the way to receive communion in the hand. Your dominant hand is placed under your non-dominate hand. With fingers closed and palm flat and parallel to the floor, you create an altar for the reception of our Lord. Observed in this fashion it will be difficult to receive communion irreverently (unless at the same time you are also sticking your tongue out thoroughly confusing the person distributing.)
THE PINCHASAURUS (Sometimes know as Birdus Beakodiosus) As communion is about to be placed in the hand of the recipient, a "pincher" known in some circles as the Bird Beak of Snatchiness jumps out and tries to snatch the host out of the hand of the minister. The pincher can sometimes be quite persistent. In worse case scenarios one must use the incantation, "Stop it!" and then whack the person on the head and when they open their mouth to say, "Ouch," you place the Eucharist on their tongue and promise them that this is what will happen every time they come to communion until they learn now to receive correctly.
THE AMBIDEXTROUS It may be obvious to YOU into which hand the Eucharist should be placed (couldn't he see my pinkies were overlapped?) but it is not to everyone else. Please don't make the minister have to guess.
LAYITONMEOUS - Often leads to popping Jesus in the same way pills are popped. Again if you only have one hand, receive on the tongue. Unfortunately I am blind in one eye so if you hold out only one hand, I won't see it and will resort to distributing to you on the tongue. (Yes, I am kidding, I can see with both eyes. Just not at the same time.)
THE POSTUS SLOTUS - Please deposit one host. No.
THE RICEUS BOWLUS - Rice bowls are general good for collecting money for Catholic Relief Services and for, well, rice. Doesn't work so hot for communion. It may be that you are crippled up with arthritis, but in such cases, please receive on the tongue.
THE MODEST MANUS - I find it strange that persons who don't mind showing their mid-drifts or legs beginning just below the hips will be modest about exposing the skin of their hands in church. Please let me assure you that not only, at least in the instance, is it alright, it is also mandatory.
THE PIUS MANUS - Actually NOTHING should be in your hands, not even something that we would otherwise consider holy.
THE NOTA BENE - Have the answers to your final written in the palm of your hand? A reminder to pick up milk? A phone number? More information than we need. Only the pure of heart shall see God and only the clean of hand shall receive Jesus.
We believe this is the Body and Blood, Soul and Divinity of our Lord Jesus Christ. Proper reception of the Body and Blood of our Lord gives great witness to this miraculous gift He has entrusted to us.
