I'm sure that Becky's façade will crack soon enough. It's also an interesting contrast to what is going on with Joyce, who hasn't had the whole fundamentalism thing crumbling around her for *years*, and that time to process things. It has been a couple of months for Joyce that is tearing down her entire world view, so she seems to be becoming more bitter and angry. Since some of Joyce is autobiographical for Willis, this may in some ways echo how he became an atheist. For Becky, despite what she has been through, god is still answering lesbian prayers, and accepting things like evolution, and budding feminism wouldn't be out of place in more liberal churches.
