The two following videos were pointed out to me recently and they really shed light on the situation of receiving communion in the hand and why it is best to receive on the tongue. Anybody who claims belief in the Real Presence cannot deny the facts. I find it hard to believe that someone will wantonly continue receiving in the hand after watching these.
Do you believe that God is really present in the Eucharist? In each tiny particle? If not, “Let him be anathema!”
