CHRIST IS ENTIRELY PRESENT IN EVERY PARTICLE OF THE CONSECRATED HOST, THEREFORE LET’S AVOID RECEIVING COMMUNION ON THE HAND

"Just like the sun cannot be divided, neither can God and Man be separated (that is, Christ, true God and true Man, cannot be divided) in the whiteness of the Holy Host. Let us suppose that the Sacred Host could be divided: even if it would be possible to fragment the Holy Eucharist into thousands of tiny Particles, in each one of the tiny Particles there is the presence of Christ, the whole God and the whole Man (that is, the whole Christ with His Body, Blood, Soul and Divinity). In the same manner that a mirror would shatter into thousands of pieces, the Sacred Host will not shatter or divide the image of God and Man that you see in the Host; the image of God and Man is in each fragmented part."

Saint Catherine of Siena

Receive Communion in the State of Grace, Kneeling and on the Tongue

The modernists rebuked Pope Pius X, so that he would allow them to receive Holy Communion standing, on the grounds that the Israelites had eaten the paschal lamb, symbol and promise of the Eucharist, standing.

The answer of the Pope was:

“One waits for symbols and promises standing, but the Reality, one receives with love and on one's knees”

H.H. Pope St. Pius X
