I don't really know what makes you think that?
No were in the game is that stated or even hinted at.
Which line specifically are you refering to?
That alone does not unlock it.
You need it to unlock the dressing/changing room in the inverted lounge to get the apocrypha.
Which you need to unlock this big ass sealing barrier where normally I think the confessional was located.

After unlocking that you can try the aids inducing jump quest section

(imagine transparent flames in the emote eyes)
or go back to the rest area and dunk the cross in the fountain.
