I have run across this is various reading down through the years, of which I don’t have a record. However, I am currently reading in the book This Is Our Fathi by Michael Francis Pennock on page 39 paragraph 2. This book is I will be using for an online CEU class this coming month. He is referencing the CCC-331 page 96. The quote here is In fact, Jesus Christ is the Lord of the angels because they were created through** and for him. But I have seen this wording many other places too over the years and wondered about it then.
Here is CCC 331:
Christ “with all his angels”
CCC 331 Christ is the center of the angelic world. They are his angels: "When the Son of man comes in his glory, and all the angels with him. . " They belong to him because they were created through and for him: “for in him all things were created in heaven and on earth, visible and invisible, whether thrones or dominions or principalities or authorities - all things were created through him and for him.” They belong to him still more because he has made them messengers of his saving plan: “Are they not all ministering spirits sent forth to serve, for the sake of those who are to obtain salvation?”
The above CCC 331 references:
Col 1:16 For in him were created all things in heaven and on earth, the visible and the invisible, whether thrones or dominions or principalities or powers; all things were created through him and for him.
The D-R Bible, Haydock Commentary on that verse:
Ver. 16. Thrones, &c. are commonly understood to refer to the celestial hierarchy of Angels, though as to their particular rank, &c. nothing certain is known. We may here observe, that the Holy Spirit proportions itself and speaks according to our ideas of a temporal kingdom, in which one authority is subject to another. In the same manner the Angels seem subordinate to one another. (St. Dionysius in Calmet) — All things were created by him, and in him, and consist in him. If all things that are were made by him, he himself was not made. And his divine power is also signified, when it is said all things consist or are preserved by him. (Witham)
