There is a good post over at the Te Deum Laudamus! blog, where a parish priest, who urges communion on the tongue, lists the seven most common Holy Communion profanations he sees firsthand:

Here are 7 common Holy Communion profanations that I see all too frequently:

• Blessing oneself with the host before consuming it. (The act of blessing with the Eucharist is called “Benediction”and is reserved to clergy).
• Receiving the host in the palm of the hand,contorting that same hand until the host is controlled by the fingers,then consuming it (resembling a one-handed “watch-the-coin-disappear”magic trick).

• Popping the host into the mouth like a piece of popcorn.

• Attempting to receive with other items in the hands,like a dirty Kleenex or a Rosary.

• Receiving the host with dirty hands.

• Receiving the host,closing the hand around it,then letting the hand fall to the side (as if carrying a suitcase) while walking away and/or blessing oneself with the other hand.

• Walking away without consuming the host.

• Giving the host to someone else after receiving (including animals)…yes,it happens!

 I am glad to see a priest who so greatly cares about the proper treatment of the Body and Blood of Our Lord.  In order to assist my readers, let me condense these common types of profanation into one, easy to understand element:

Communion in the hand.

The priest in the post cites to paragraph 92 of Redemptionis Sacramentum:

“[S]pecial care should be taken to ensure that the host is consumed by the communicant in the presence of the minister,so that no one goes away carrying the Eucharistic species in his hand. If there is a risk of profanation,then Holy Communion should not be given in the hand to the faithful.” (Paragraph 92)

His conclusion:

When Holy Communion is received on the tongue…every single one of these abuses is instantly eliminated!

The way we treat another person says more about our relationship with that person than any words we might say. This is especially true of our relationship with the Divine Person,Jesus Christ. So let us continually seek to increase our reverence for our Eucharistic Savior,and to eliminate anything that degrades the respect He deserves.
