I do believe this was the church that Mrs Durham attended:

This particular church, back then, permitted other clerics to use its facilities for a modest fee.

Her favorite advanced a Liberation Theology with Communistic politics folded into a pan-theocratic stew. It was real cutting edge. It must have really appealed to her supremacist impulses.

Such emotions flowed during her workday: she ran the cashiers like a Drill Instructor.

That her troopers were all female and smart and not paid so well also put a real burr up her backside. She was a hyper-feminist, before the term arose.
