“I wonder if Rusty will stay a Catholic.”
That is a very good question.
Reading his story, I felt sympathy for him, but also I felt uneasy about several features of his personality. He seems to have a tendency toward depression, and also always seeking answers that lead him off into new pastures.
Notice how he tends towards what AA terms the “geographic solution”, whenever his problems get overwhelming, he moves somewhere else. But then ... the problems start up again. Also, note that the Orthodox priest was unwilling to baptise him, but suggested that he wait. This proved a sound suggestion, as he soon gave up on the Orthodox Church, but I wonder what the Priest observed which led him to that conclusion.
So he has taken the bait. But it is still in question whether he will spit out the hook or whether our Lord will set it firmly and reel him in.
