84 In this regard We wish to offer Our praise and encouragement to the studies that have been carefully and prudently carried on in many areas under your leadership and auspices, to improve the religious training of both youngsters and adults by presenting it in a variety of forms that are specially adapted to local circumstances and needs. All of these efforts are useful; but on the occasion of this centenary, God wants to cast new light on the wonderful power of the apostolic spirit, that sweeps all in its path, as it is exemplified in this priest who throughout his life was a witness in word and deed for Christ nailed to the cross "not in the persuasive language devised by human wisdom, but in a manifestation of spiritual power." (88)
