I don't know. You're reading way too much into Batman's Church of the Redeemer.

It's another new age service catering to the lost, the damned, and the ignorant. Perhaps it becomes Scientology but I think that faith dies hard. Because the believer is built on the bedrock of undying platitudes. But in any mediation provides an opening in signs of solidarity. Will it be attended, not when the Mosque, or the Church, or the Synagogue has such fervor.
