"Take this and eat it, all of you": communion
It is in keeping with the very meaning of the Eucharist that the faithful, if they have the required dispositions, receive communion each time they participate in the Mass. As the Second Vatican Council says: "That more perfect form of participation in the Mass whereby the faithful, after the priest's communion, receive the Lord's Body from the same sacrifice, is warmly recommended."
