This is interesting. So, Father Feeney is saying that those with BOD, like those before Christ, go neither to Heaven nor to Hell, but to Limbo? I don't think I've ever seen this explanation before. If so, he does not sound like he is denying BOD.
That's not what he's saying. All he is saying is OT saints went to limbo, not to heaven or hell. Which is to say they died justified and went to Limbo, whereas the common belief is that the BOD person goes straight to heaven.
He says: The problem Trent had to deal with was -
"A man in the Old Testament waiting and wanting Baptism to be instituted, and a man in the New Testament waiting and wanting Baptism to be administered could both be justified." However, Trent cleared up whatever confusion there may have been when they stated; since the promulgation of the Gospel, justification cannot be effected without the laver of regeneration.
Which is to say, per Trent, Fr. Feeney was simply mistaken when he said a NT man waiting for and wanting baptism could be justified.
