1. Catholics and Protestants have different understandings of the work of the Holy Spirit. Historically, the Catholic understanding has been more implicit than explicit. And today the explicit understanding of the Spirit for many Catholics may be derived from Protestant ideas. Instead, I find Fr. Luigi Giussani's description of the Holy Spirit's work to shed light on the traditional Catholic understanding: "The Spirit is what makes us perceive God in the light of the senses, it enables us to experience Him. The Spirit is the principle whereby God, who is invisible, becomes perceivable" (Book of Hours, Wednesday).
2. For Catholics, what are the great examples of the work of the Holy Spirit?
- The Annunciation to Mary;
- The Transubstantiation of the Eucharist (Eu-Charis);
- Charisms, or gifts of the Spirit to the Church through the saints (on earth or in heaven). "A charism is an ultimate terminal of the Incarnation, that is, it is a particular way in which the Fact of Jesus Christ Man and God reaches me, and through me can reach others” (Giussani).
4. This answer is complicated by the prevalence of fideism among Catholics, who – like everybody else – tend to think of salvation as escape from the body and circumstances instead of discovering the vanishing point of destiny in the everyday.
