I agree with BlestOne, unless this person has been a friend of yours for many years. If only a recently acquired “friend” then most likely this person is “friendshipping” and you’re just a port of call.
BTW this is typical among fundamentalist types as well. I’ve run across many like this, some on this forum. They appear and strike up a conversation on the side, and express how much they care about you, want to help you get rid of that ol’ debil Catholicism! Once it becomes clear to them that you are not going to swallow the hook, they will disappear and go looking for the next fish.
One term for this tactic among evangelicals is “friendship evangelization.” Make a friend, be a friend, bring a friend to Jesus. I don’t find these types of friendships any less shallow than the ones Mormons develop, for the same purposes. If you’ve got anything in common upon which to base a real friendship, then it won’t have that much to do with your respective religions. And it doesn’t appear likely that you’ve got religion in common, unless you convert to Mormonism, or your friend converts to Catholicism. The fact that he/she is plying you to interview the bishop is a sign that you’re the one being cultivated.
