From the National Catholic Register, with Father Zuhlsdorf's emphases and comments:
"Recently there has been a rash of desecration of the Eucharist during communion time. As a result, there have been some calls to restore communion on the tongue. [Do I hear an "Amen!"?]
That is one solution.
Here is another.
A priest in Valencia Spain witnessed a young man during communion take the Eucharist and throw it on the floor. The priest then decided on a course of action that one could properly call old school apologetics of the corporal kind.
The priest slapped the young man across the face and dragged him from the Church and loudly pronounced him a ‘blasphemer.’ [OORAH!]"
