With regard to the potential for abuse of consecrated hosts (and I apologize if anyone has already mentioned this), I believe strongly that we should return to communion on the tongue, NOT in hand, ever.
In fact, I like the Orthodox method:
- Communion is given to known parishioners
- They are called by their Christian name (whether that is their birth or confirmation name in the case of a non-Christian birth name) when taking communion
- To attend a different church, one requires a signed form from their priest confirming that they are Orthodox, etc.
- Communion is NEVER taken in hand
At first, when I read about all that, I thought “what a hassle!”…but it would prevent scenarios of stolen consecrated hosts as well as non-Catholics/non-believers going up for communion just because everyone else is when they have no concept of what the Eucharist is (something that can happen at a wedding or funeral where mixed backgrounds come together).
