It’s true that when the Anglican Primate celebrated ‘Mass’ at the local Anglican parish I had to keep reminding myself that this was not really Mass and that no Eucharist was actually happening. We were there in the context of the Week of Prayer for Christian Unity which just happened to coincide with the Primate’s visit.
Communion was different in that they all received kneeling at the altar rail. But when my Pastor went up to receive, followed by a few of our parishioners who had, until they saw him go up, made no motion to do so, I realized why people are confused and don’t know the difference.
