EWTN Catholic Q&A
Receiving Communion under both species
Question from Lucille on 02-03-2013:

Why is Communion sometimes distributed under both species, since each species contains both the body and blood of Christ?

Answer by Catholic Answers on 02-04-2013:


Receiving under both species is a fuller sign of the sacrament. Even so, the only person who must receive Communion by both species is the celebrating priest. For everyone else, to do so is optional because a full Communion is made under one species alone.
