I remember when I was a kid and made my first communion, our teacher, a wonderful nun, had covered almost every possible detail with us. We practiced, and had most everything down perfectly. The one thing she didn’t tell us, however, was when to sit after communion! So, during communion, after I had received, I decided sometime during the communion processional that I was ready to sit, and so I did. Later on, my mom told me that I should kneel until the priest sat down… so I have always remembered that! I always remembered that I had “messed up” something during first communion. (My mom didn’t make me feel guilty, I made my self feel guilty!)
Later on, I started kneeling until the tabernacle was closed, or until the priest sat down, whichever one happened last.
Our archdiocese now stands during communion, which was just implemented within the last 2-3 years. At first, I didn’t like it at all, but the priest at the parish where I first heard about it didn’t explain it very well. Later, I was at another parish where the priest explained it much better, and I understood and accepted the standing posture better.
Our new archbishop is currently addressing some variations on posture during different portions of Mass, and he wrote an article in our diocesan paper explaining some of the things, and he had this to say:
“Standing during the distribution of Holy Communion: The posture for receiving Holy Communion, as established by the U.S. bishops, is standing. The assembly will stand for the distribution of Holy Communion after the response, “O Lord, I am not worthy. … I shall be healed.” The standing posture covers the priest’s reception and continues for the distribution of Holy Communion to all the faithful. This posture best expresses the communal nature of this part of the Communion Rite and acknowledges the presence of Christ in the midst of the assembly.”
We are also encouraged to have a period for silent prayer after communion. The archbishop also wrote:
“Period of silent prayer after the distribution of Holy Communion: After everyone in the assembly has received Holy Communion, the celebrant and the faithful will kneel or sit for silent, individual prayer to “praise and pray to God in their hearts” (GIRM no. 45). Since this period of prayer is private and individual time, the faithful are given the choice of kneeling or sitting for this prayer. During this time period, when there is no movement or music, there should be a one- to two-minute time period for individual prayer.”
However, most priests I have experienced do not give much time to this portion, especially if Mass has run long… (probably because they can see the Mass exodus of people after communion… If it weren’t for fire regulations, I would say we should chain the doors shut until Mass ends!
