I happen to belong to St Aloysius, in Pee Wee Valley, KY, which is where Father Dave Harris is the Assistant to the Pastor. All who know him, I’m sure, would agree that there is no doubt that he is truly, in every meaning of the word, a Catholic.
As to whether or not his wife and children have converted, I have no idea. I know that I have never seen his wife. I’m guessing, when I say that, she probably stays away from our parish to keep things simple for him in his role as our priest.
One draw back to being a married priest is that he can only ever be the Assistant to the Pastor. He’ll never lead his own church as Pastor.
On a side note: In addition to all of his other life accomplishments, Father Dave is a Fourth Degree Knight of Columbus, which not that many people attain.
