Fr. John Perricone establishes the topic, “Angels and Archangels,” by citing Thomas Aquinas, who writes that the existence of angels is so absolutely established, that certainty in this truth surpasses even certainty in the Laws of Nature. What follows is an engaging discussion on the traditional Catholic beliefs about angels, the significance of angels in art and the central roles of angels in the Old and New Testament. The talk then turns to the continual strife between God’s faithful angels and the fallen demons. This talk concludes with a mediation on the Annunciation when Gabriel appeared to the Virgin Mary and she became the mother of God.
