The Purpose

 Not everyone on a communion line will have the same response to the host they receive.  If they receive a couple times a year, holidays, family visits and such, I doubt that the host means much.  They see with the physical eye that the host is a round white wafer.  They taste with the physical tongue nothing much.  Sacraments, to be effective, must be approached from a heart level.  Someone why sees with the eye of the heart, and tastes with the heart of the tongue, will have a rather profound experience of that wafer.  Persons receiving at this level, depth, might then be able to see beneath the actions of others, hear deeper than the words spoken, and then speak with the tongue of the heart to the pain buried deep with that other person.  Jesus on the cross saw in his public executioners something deeper, some pain they buried, so that they could do what they do.  And he said, “Father, forgive them, for they know not what they are doing.”
