At this point in chapter six, we commence a tour of various persons who attract devotion as role models, and individuals of persuasion, so we think, at the throne of God. The next five numbered sections take a look at angels. Let’s begin with a short section of two paragraphs:
213. With the clear and sober language of catechesis, the Church teaches that “the existence of the spiritual, non-corporeal beings that Sacred Scripture usually calls ‘angels’ is a truth of faith. The witness of Scripture is as clear as the unanimity of Tradition”(Catechism 328).
In the Church’s view, the witness of the Scriptures of both Judaism and apostolic Christianity are enough to convince. Angels are not mere window (or shoulder) decoration. They serve God and assist persons according to God’s plan.
Tradition regards the angels as messengers of God, “potent executives of his commands, and ready at the sound of his words” (Ps 103, 20. They serve his salvific plan, and are “sent to serve those who will inherit salvation” (Hb 1, 14).
