I'll take it a step further, Dulcamara. If one refuses to have anything to do with non Catholics, who do they go to for health care, groceries, car repair, etc, etc. God must have gifted these people for them to be able to do the things they do.
Chesterton was gifted. He would get so deeply into his thoughts that he would get lost. One day he telegraphed his wife from down town to ask her where he was going.
