The church was designed by Cyrus Pinkney, with the financial backing of Judge Solomon Wayne, Bruce Wayne's great grandfather. Solomon Wayne was often allowed to give guest sermons, due to his harsh sense of justice and urge to drive the malevolence from Gotham City.
Arkham Origins Incident
Black Mask was keeping a horrendous amount of drugs in the Church. Batman destroys the last drug stash before confronting Sionis and his men, defeating them, and leaving Sionis to be arrested by the GCPD.
Before Arkham City Incident
Aaron Cash chose to situate his medical team within the Church. Knowing full well that they could only rely on a minimum amount of support from Strange, Cash had to ask and beg for medical supplies and equipment.
Bruce Wayne was the first to donate, sending security shutters to seal the building as well as cutting-edge body armor and supplies. Upon hearing of this development, Hugo Strange angrily locked down all supply routes from the medical team's location.
Arkham City Incident
After saving Catwoman from being shot by the Joker, Batman uses his Detective Mode to trace the trajectory of the sniper shot. Aaron Cash with his team of medics and security guards were stationed at the Church until Harley Quinn and four of Joker's Henchmen come and hold them hostage. Hush is disguised as one of the medics.
Medic Adam Hamasaki said that Hush went insane and cut his own face off. He is unconscious on a medical bed gripping a mysterious medical tool box. Later, his body is missing.
Batman later climbs to the Bell Tower to investigate the mysterious gunshot. He discovers that Joker shot a remote controlled sniper rifle and that the Bell Tower is rigged with explosives. Batman leaps from the window as Bell Tower explodes.
If Batman comes back, he discovers that Cash and his team were kidnapped by the Riddler. He goes to Arkham City, solves Riddler's riddles, and saves each hostage.
