Join Fr. Dave Dwyer, CSP, as he explains the do's and don'ts and rights and wrongs of receiving Communion. Should Catholics receive communion on the hand or on the tongue?  And how exactly are we supposed to do that reverently?  Is there any other acceptable response besides "Amen?"  ...and what does "amen" mean anyway? The Church calls the Eucharist the "summit and source of our faith," so it would seem pretty important to understand the basics about receiving this sacrament when we go to Mass.
