Great post. I’d like to re-add this to it:
From the General Instruction on the Roman Missal
Manner of Receiving Communion
#160:2: The faithful are not permitted to take up the consecrated bread or the sacred chalice themselves, and, still less, hand them to one another. The
norm for the reception of Holy Communion in the dioceses of the USA
is standing. Communicants should not be denied Holy Communion because they kneel. Rather, such instances should be addressed pastorally, by providing the faithful with proper catechesis on the reasons for this norm. **When receiving Holy Communion, the communicant bows his or her head as a gesture of reverence **and received the Body of the Lord from the minister.
The consecrated host may be received on the tongue or in the hand at the discretion of the communicant. When Holy Communion is received under both kinds, the
sign of reverence is also made before receiving the Precious Blood.
