It appears that underlying the issue of returning to Communion rails are two issues, although not addressed directly in this thread.
One is CITH, which tends to elicit reactions negatively, including in other threads, a judgementalism that those who do so are either not as reverent, or do not believe in the True Presence. Given nothing more than idle speculation, such comments and attitudes should be addressed for what they are. Going back to altar rails pretty much makes CITH at best awkward.
The second issue seems to carry some angst towards reception from the Cup; likewise, reception at an altar rail removes the possibility of the issue, thereby eliminating it.
I happen to be a member of a parish for 30 years, +/- and in that 30 year period, in a church built in the half-round, without altar rails, with the Risen Christ on the wall (and 3 crucifixes within the sanctuary during Mass), with the vast majority receiving CITH, and somewhere between 1/3 and 1/2 receiving also from the Cup, we have also managed to produce 3 priests, 2 deacons, 2 women professed religious (who wear habits), and one current seminarian in first year theology.
What makes us different than the implications of at least one of the posters (who implies numerous people receiving without believing in the True Presence)?
We have had Perpetual Adoration for about 25 of those years.
It is just plain pure poppycock that you have to have altar rails for people to be reverent, or that altar rails induce belief in the True Presence. Catechesis does that.
There may be some dioceses in the US where there are liturgical abuses. a deacon sitting out distribution of Communion may or may not be one, as there may be legitimate reasons for that. But I sort of suspect that if a survey was done of the 18,287 deacons in the US, that one would find even a small percentage of them “sitting it out” without a valid reason (and the same can be said for priests).
I get the fact that the auxiliary bishop of Kazakhstan is a favorite among Traditionalists, but personally I have a problem with a bishop - auxiliary or otherwise of a foreign country, indirectly coming in and saying publicly that the USCCB doesn’t seem to know what it is doing.
The norm in the US is standing. Kneeling is not outlawed. And proper catechesis is the issue - not altar rails.
