ISB ~ Hebrews 1 v14

ministering spirits:The angels are protectors of the saints, mediators of grace, and ministers who offer the prayers of God’s people in heaven (Ps 91:11; Acts 12:11; Rev 8:3-4) (CCC 331-36).

• All angels have the same nature among themselves; nevertheless, some of them stand over nations, while others are present beside each one of the faithful (St. Basil the Great, Against Eunomius 3, 1).
