Sounds a bit far fetched to me. According to Pope Benedict XVI in 2007, receiving on the tongue is the normal way to receive and you need the local bishop to allow reception on the hand. But most catholics have it backwards.
The dangers of receiving on the hand are related to both hand sanitation, you just entered a building and touched various surfaces and shook hands with those around you. And more importantly particles from the host will remain on your hand and every bit of the host is our Lord. This may seem trivial to some but that only demonstrates the lack of awareness and reverence of many of the layity do to tge casualness of current practices.
As for breathing on the priest’s hand, I never breathe when I’m eating, do you. You open your mouth and automatically stop breathing for a second. You don’t think about it but you do.
So why do priests and EMs, I am an EM, not know how to properly distribute the Body of our Lord correctly. They often seem upset about it and don’t know that they should hold up the host with their thumb facing themselves and simply place it on the tongue or hand and slide their thumb forward.?
True. But that is not the most dangerous mechanism of transmission. And that can be avoided if those dispensing (and receiving) wear gloves. I've never seen that suggested, but it is a viable solution.
"And more importantly particles from the host will remain on your hand and every bit of the host is our Lord. This may seem trivial to some but that only demonstrates the lack of awareness and reverence of many of the laity due to the casualness of current practices.
And particles of the Host are shed into the air and onto the floor with communion on the tongue as well as the hand. The effective difference between "in the hand" and "on the tongue" is nil.
"As for breathing on the priest’s hand, I never breathe when I’m eating, do you. You open your mouth and automatically stop breathing for a second. You don’t think about it but you do.
Yes, you stop breathing ONCE THE FOOD IS IN YOUR MOUTH, but you are breathing either in or out as the priests hand is approaching your face.
"On the tongue" communion is being restricted because the danger is real, not some nebulous conspiracy to denigrate the Host.
