I've been around the Church for a long time (and interacted a very little bit with senior leaders), and was a Church employee before health issues ended that. I very highly doubt that anyone "will lose your ... pension if you stop regularly attending church services or giving 10% of your paycheck back to the church".

But job, yes. They want people who are devoted, if they are going to pay them to further the work. To me that makes perfect sense.

(Thoughtful comments appreciated with downvotes; thanks.)
