We are going to have to die in a state of grace and ask him to know with certainty. However, notice the similarity between the blindness of Saint Paul and of the elder Tobit in the second chapter of the Book of Tobit.
In both cases, mysterious (to us) presences ministered to Saint Paul and Tobit at God’s request. The Archangel Raphael is mentioned only in the Book of Tobit, but testimony in that book comports exactly with New Testament revelation. As well, the “Ananias” who obeyed God’s command and anointed Saint Paul’s eyes is otherwise unknown in the scriptures.
Saint Raphael literally disappeared from sight and Ananias scripturally disappeared, which I find curious and intriguing.
