Apparently, religions have rules for how people are supposed to behave when the church's religious leader leaves. These are interesting to research.
Episcopalians be like: "There is no need to end friendships..."
Catholics be like: "Continuing friendships will be important, but it must be made clear that the pastoral relationship has come to an end."
Presbyterians be like, "While friendships with the
departing pastor will surely continue, the pastoral relationship must not."
Quakers be like: "We're all friends."
(Many) Jews be like, "We're all family! Of course I'm here for you!"
Evangelicals be like: "People from your former
church may still contact you, but the type of communication
you have must change."
United Church of Christ be like: "Friendships don't end, but pastoral relationships do."
Unitarian Universalists be like, "YOU ARE DEAD TO ME!"
