I have only ever seen one Catholic parish set up this way, and like yours, the altar was in the middle, rather than on one end. I think this is a modern (post Vatican II) style of church design, and personally, I find it totally distracting.
Yeah, I get what you mean. In my parish, at the Mass I go to there is a lady whom I frankly think is a little weird. It’s hard to describe, but she worships in a distracting way. She kneels at improper times, waves her hands around distractingly, covers herself with a hood during consecration, wears bizarre clothes, does a bunch of other weird things. If our pews faced the front, I’d be able to ignore her, but it’s difficult to do it when she’s right there where I’m facing. I try to just keep my eyes on the floor, but it doesn’t work as well as I’d like. Also I’d much rather keep my eyes up, facing the altar.
There’s another good question: would anyone be able to tell me how I could work through this? I’m trying to take this as something that is my problem and not hers, and I just need to figure out how to worship without being distracted. Taking another seat is an option, but this parish (though it is a Cathedral) is rather small; seating is limited, and even then, because of the peculiar arrangement of the pews and the altar, it still wouldn’t be easy to ignore her. The seating is set up rectangularly, almost circularly, making it hard to find a good spot where I wouldn’t have to worry about being distracted by her.
I guess another option would be to complain to a priest so maybe he could talk with her (and I do know that I’m not the only one who finds it distracting), but I don’t know, that doesn’t feel like the right thing to do for some reason. Any ideas?
