There’s no way I could know, since I’m banned from being anywhere remotely near the sanctuary during the times the Temple Beth Shalom is using it.
That is the big problem. Inasmuch as you have access to the Adoration Chapel, you and the rest of the parish should not be denied access to the church.
I would suggest that you also write to the diocesan administrator whom the College of Consultors elected. I went to your diocesan website and no mention of this situation was made in the E-pistle.
While there are those who may not seem to think that this is a big problem, I think it is. This is a very different situation from one that I was involved in some time back. About eight or nine years ago, a couple asked our bishop for permission to have their wedding at the Cathedral. They were Methodists. Interestingly enough, the groom’s uncle was Jerry Jones (yes, that Jerry Jones, the owner of the Cowboys). The cathedral is the largest church in town. The wedding was going to take place after the anticipated Sunday Mass.
The bishop agreed, but, since the rector was going to be out of town, our deacon stayed behind to make sure that things were done properly. I also stayed with the wedding coordinator. The deacon, taking the humeral veil, removed the Blessed Sacrament and placed the ciborrium in the back chapel (that we use for Holy Thursday). The couple agreed to be respectful of the sacred space. Nothing was place on the altar and everything ran smoothly. Oddly enough, Jerry let the altar servers (who stayed behind so they could meet him) hold his championship Superbowl ring and take pictures with him while each kid wore the ring (outside the cathedral). After the wedding, the deacon replaced the Blessed Sacrament back into the Tabernacle and everything looked as though nothing had happened (except for the floral arrangements). No one was displaced.
This was an entirely different scenario from what you described. It was a one and done deal. Interestingly enough, there were some folks who came in and out to visit. No one was shut out.
Questioning a decision that does not seem right is in no way being disobedient. You have a legitimate concern. There is something disconcerting about not being able to go inside your own house. It’s like when you have distant cousins visiting. You let them visit, but, you don’t let them take over your house.
