And all of the things you mention depreciate from the sacred priesthood and from the reverence to the Blessed Sacrament, and are cause for reparation.
There was never a "need" for laymen to administer Holy Communion until this "need" was created, against the express will of the Holy Father, by recalcitrant bishops like the former Cardinal Bernardin and others.
And there is never a need for girls to serve at the Holy Altar. The "need" is artificially created. But the Americanist, feminist Moms certainly feel less cheated though.
If two-thirds receive in the hand, then that means the CRUMBS left over on the hands fall to the ground and are trampled underfoot. I am not speaking of the times of entire hosts being dropped. And if communion is given from the chalice, then Precious Blood WILL be spilled. It is only a matter of time.
"Crumbs" that one would need a microscope to see. You're engaged in particlitis, a form of scrupulosity, Mershon.
I wonder how many crumbs fell from the Consecrated Bread that was taken home by members of the early Church for consumption during the week.
