The problem, I think, is that you’re mixing and matching contexts, which makes the whole picture harder to visualize. What you’re saying is true, but not clear (IMHO). So, when you say “Receiving under one kind is not normative, at least in the U.S.”, you’re kinda right and kinda wrong:
- Communion under both kinds is not optional [for the celebrating priest].
- Communion under both kinds is always possible [for concelebrating priests, deacons, and perhaps other ministers].
- Communion under both kinds is optional [for the congregation, depending on what the bishop (or conference of bishops) has decided].
So, if you mean to say “receiving under one kind is not normative
for the priest celebrant,” then I’m with you. If you mean to say “receiving under one kind is not normative
for the congregation, at least in the U.S.”, then I think you’re misstating what the Church says. I don’t think you’re
trying to misstate the teaching, but without making the distinction between ‘celebrant’ and ‘congregation’, it’s easy to get confused…
Maybe that’s where the disconnect is. I wasn’t disagreeing that it
was forbidden (to the congregation) in the past; I was disagreeing that it
is forbidden now. Look back at Reuben’s statement (which I quoted): he stated that it
is forbidden (not “was forbidden, but now permissible”).
