Chapter 36 — Part IV: Prayer — The Second Petition: Thy Kingdom Come
Section 18. This kingdom is called justice, because it has for its basis the justice of Christ the Lord. Of it our Lord says in St. Luke: The kingdom of God is within you. For although Jesus Christ reigns by faith in all who are within the bosom of our holy mother, the Church; yet in a special manner He reigns over those who are endowed with a superior faith, hope and charity, and have yielded themselves pure and living members to God. It is in these that the kingdom of God's grace is said to consist.
