And I meant extreme fragmenting.
It does not matter how small is the fragment. Jesus is equally present regardless of the small size of the fragment. That is one reason why Communion in the hand is such a horrible sacriligeous practice - because inevitably in passing the Host from the ciborium to the recipient's hand, tiny fragments fall onto the floor and are trampled by other communicants.
That tiny Fragments detach and drop from the Host is the reason why in the true believing Church, a communion plate is
always held under the chin of the communicant; then after the Communion the priest is very careful to collect all those Fragments, which are the Body, Blood, Soul and Divinity of Our Blessed Lord, and put them into the Chalice from which he consumes them.
I hope you understand now, that however small is the fragment, it is nevertheless the Body, Blood, Soul and Divinity of Our Lord and Saviour Jesus Christ.
