John Amos is a pastor who wants to end Bo Hopkins' moonshining operation, which is poisoning and blinding drinkers. But to do it he has to call in the A-Team.
Hollywood has always been funny about Christianity. Even back on the days when it was respected (no more) it had curious treatment. It was mostly in small towns where everyone in town went to the same church (try that in any small town in America where we have freedom of religion . . . Or freedom of no religion, if you prefer; but that doesn't apply here).
All preachers and pastors have to wear a collar to segregate people who are professionally religious, the people who may be religious out of church hours.
The sermons, such as they are, are non-specific denominationally. The hymns are non-specific (the worst offender is "Sergeant York" where Walter Brennan leads the congregation in "Give Me Rhat Old Time Religion")
Especially on TV pastors have to be shocked easily, though in real life they come from various, often shabby, backgrounds before finding the Lord; and, in any case, preachers are often the first people folks come to when they have terrible admissions, and they've heard it all (again, that doesn't apply here).
The A-Team has already gone up against Hillbillies. Now it's their cousins, the moonshiners. Or is there more them than shine? They have lots of surveillance equipment to protect mere stills.
