Well, I’m not sure if this will help, but here’s some of what the Catechism says on angels:
The existence of angels - a truth of faith
328 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.
Who are they?
329 St. Augustine says: "‘Angel’ is the name of their office, not of their nature. If you seek the name of their nature, it is ‘spirit’; if you seek the name of their office, it is ‘angel’: from what they are, ‘spirit’, from what they do, ‘angel.’"188 With their whole beings the angels are servants and messengers of God. Because they “always behold the face of my Father who is in heaven” they are the “mighty ones who do his word, hearkening to the voice of his word”.189
330 As purely spiritual creatures angels have intelligence and will: they are personal and immortal creatures, surpassing in perfection all visible creatures, as the splendor of their glory bears witness.190
The angels in the life of the Church
334 In the meantime, the whole life of the Church benefits from the mysterious and powerful help of angels.201
335 In her liturgy, the Church joins with the angels to adore the thrice-holy God. She invokes their assistance (in the funeral liturgy’s In Paradisum deducant te angeli. . .“May the angels lead you into Paradise. . .”]). Moreover, in the “Cherubic Hymn” of the Byzantine Liturgy, she celebrates the memory of certain angels more particularly (St. Michael, St. Gabriel, St. Raphael, and the guardian angels).
336 From its beginning until death, human life is surrounded by their watchful care and intercession.202 "Beside each believer stands an angel as protector and shepherd leading him to life."203 Already here on earth the Christian life shares by faith in the blessed company of angels and men united in God.
One of my favorite quotes is:
“If angels could be jealous of men, they would be so for one reason: Holy Communion.”
~St. Maximilian Kolbe
