If I might intrude, Sister, one must carve their own niche here, in regards to the Chantry.
I am bound to at least outwardly be of a faith called Catholicism, but that is because I'm prince of a country whose official religion is Catholicism. I have my altar hidden at home, carved just like the one I remember from Kirkwall. You do not have to hide it, but I do, because it is personal to me. Even my fiancee knows to leave me be at those times.
I believe the Maker hears everyone, everywhere, in whatever language or verbiage they use to speak to Him. Don't lose faith; adapt it. I wish you luck.
