Given my interpretation of the linked article, I’d suggest that James Foley is a dirtbag.
In fact, were Foley actually doing something worthwhile, we wouldn’t be hearing about him everyday, IMHO.
James Foley was baptized, received first communion, and was confirmed at our church. I knew the Foleys before Dr. John moved to Dover but I did not know Jim.
Those who grew up with him say he was devout. He was on video saying the Rosary during his earlier captivity in Libya.
I personally have no doubt that he did not renounce Christ (or we would know). I personally have no doubt that he was selected from among the other prisoners because he was a Christian.
