There's the story in the life of St. Peter Claver regarding the slave girl Augustina who died. He raised her back to life, thinking she couldn't enter Heaven because she needed to confess, but it turned out that it was because she hadn't been baptized (evidently unbeknownst to anyone). She was by all appearances a devout Catholic, assisted at daily Mass and received Holy Communion every day. But she was not permitted entry to Heaven because she was lacking her "wedding garment" ... as she related to St. Peter after having been raised back to life.
