Why is Holy Communion offered on the hand as well as the tongue? No matter how well one cleans their hands before Mass they still aren’t clean enough to handle the Sacred Host.
Our hands are a lot easier on the host than the acids in our stomachs. Our Lord was quite willing to get dirty when He joined us in our human journey. Dirt does not keep Him away from us. Sin is actually far filthier than dirt. But even sin did not keep Him away from us. But it does keep us away from Him. We tend to sin with our tongues more than with our hands.
It is sin that we need to be cleansed of before receiving Him in the Eucharist.
