I have a healthy dose of anti-religion baggage in my own closet (an Atheist teaching at a Catholic school....heh) but thought that the characters were just sweet and charming enough to keep this surprisingly light story from being too preachy. The OMG-I've-just-fucked-a-minister dilema was just the right amount of awkward and realistic and the OMG-I've-just-smoked-weed-with-a-minister moment which follows soon after was pretty funny. Both characters positively sizzle right at the get go and the chemistry is good, but I do prefer a little more tension and a little less predictability before we get to the HEA.
Kudos to the author for tackling this very sensitive subject.
