Why do not more priests insist that the Body and Blood of Christ must be received by mouth, preferably whilst kneeling?
It seems such basic common sense, that, in order to protect the Host, reception should not be by hand.
This video clip demonstrates, very well, the issue of fragmentation.
Equally relevant is the increasing practice of people walking out of church with the consecrated Host in their pocket.
Reception by mouth eliminates the fragmentation issue and helps prevent Host abduction.
