She has known Mason for years, and been engaged for two, and they were shackin' up. And still she wasn't sure she wanted to marry him? Sounds to me like perhaps neither one of them is really ready to marry. I'd also flunk the pastor on his marriage counseling exam.
The minister gushes disgustingly about what super Christians these people are, which suggests that he is as shallow as both of them are--and as indifferent to what used to be called common decency. So I imagine that the "counseling" they received mostly had to do with the size of the various checks to be written to functionaries at his church after the circus-wedding.
