Are God, angels, and demons really invisible? Or can the spirits be seen with human eyes, through the lens of Church Ethics? The gift of discerning of spirits is indispensible to the study of church ethics. Ignatius of Loyola, founder of the Society of Jesus (Jesuits), wrote two sets of Rules for Discerning of Spirits in his Spiritual Exercises in the early 1500s. He taught how the church can receive from God the gift to see otherwise invisible angels, demons, and the Holy Spirit. Ignatius' views were influenced by John Cassian, Jacobus de Voragine, Ludolph of Saxony, and Thomas a Kempis. Ignatius' Rules are exegeted in dialogue with contemporary scholars Karl Rahner, Hugo Rahner, Piet Penning de Vries, Jules Toner, and Timothy Gallagher, and applied to one study of ecclesial ethics in the narrative theology of Samuel Wells. A four-step Ignatian "pneumato-ethical method" is developed, which any analyst can follow to see the spirits, by consolation/desolation, consent, manifestation, and pneumato-ethics. This method revolutionizes how we study ecclesiology, soteriology, missiology/world religions, liturgy, worship, Eucharist, hermeneutics, homiletics, pastoral counseling, church history, and politics. The spirits are not invisible at all. They can be clearly discerned through the lens of ecclesial ethics.
