in american evangelism actions are valued over belief. it was a common saying in my own youth group days that "going to church makes you a christian like standing in a garage makes you a car." the fact is it doesn't matter if you believe the right things if you aren't acting accordingly. you have to commit. you can't just believe that christ is the only way into the kingdom of god, you have to take every chance to spread the word to the uninitiated. you can't just privately not endorse homosexuality, you have to personally cut off your toxic codependent girlbestfriend who you have a crush on that you don't know how to handle. hypothetically.
this is why in my culturally evangelical framework, conchita is the truest snapewife. rose and tanya were frankly full of shit because if they truly believed in snape and that he was their true master and lover and that he was to be the center of their lives and that he did not share, then they'd have left their husbands. conchita is the only one who truly walked the walk even is she never managed to truly channel him "correctly" and she was fucking RIGHT about false prophets and the other wives took her dedication and shat all over it because she was geographically far away but she was right! conchita's snapism is the one true snapism!
