Incredible as it might seem after twenty centuries of Christianity, were St. Paul to ask the same question of a great many Christians today, he would receive an answer similar to that of those first disciples in Ephesus. Though the name "Holy Spirit" may be familiar to them, the vast majority of Christians today know very little of Him. But thanks to Fr. Marín, that is about to change.
