I don’t feel I can share that sentiment. A priest’s decision to stop serving as a priest is between him and the Lord, so we shouldn’t judge. Perhaps there was never any calling on his life in the first place, or perhaps he has completed whatever the Lord had intended for him to do and it is time for him to move on to something else. We just don’t know for sure. God alone knows. It’s not our business, so I’ll refrain from making judgments.
