Not sure how close he is to converting, and he was charitable in that Akin-White debate, but he often does not articulate Catholic positions well.
I heard a caller to him the other day ask him why Catholics teach infant baptism and referenced Acts 16:30-33 that because the jailer’s whole family was baptized that the Church teaches there must have been children there so let’s baptize children. Hannegraf said that the jailer’s household believed first and then were baptized…but what he missed was that this passage is 1 of at least 3 I can think of where a household was baptized, or brought to the Lord on behalf of another. Hannegraf seemingly didn’t know this or didn’t realize that the other passages don’t describe an assent to faith by the members of the household, rendering the non-Catholic to believe that none of these households or people had any infants. See Acts 16:15, Acts 2:39, et al… And he didn’t get into any of the other Catholic Scripture or Tradition on this at all, or mention that he didn’t have time to do so.
A year or two ago I heard him trying to explain to a caller who asked where Catholics came up with the idea of Mary’s sinlessness (I believe was the topic), and he just said he didn’t know, but that it was wrong.
He does seem to be charitable toward Catholics, but he just doesn’t seem to get the teachings right.
Scott Hahn and others have been guests on Hannegraf’s show as well. Scroll to bottom of this page to listen.
