Saint Nicholas: "the splendor of glory from God forever: wrapped in the cloak of justice from God, bear on your head the mitre"

"For God will show all the earth your splendor:
you will be named by God forever
the peace of justice, the glory of God’s worship."
- Bar 5:1-9


"The individual bishops are the visible source and foundation of unity in their own particular Churches." As such, they "exercise their pastoral office over the portion of the People of God assigned to them," assisted by priests and deacons. But, as a member of the episcopal college, each bishop shares in the concern for all the Churches. The bishops exercise this care first "by ruling well their own Churches as portions of the universal Church," and so contributing "to the welfare of the whole Mystical Body, which, from another point of view, is a corporate body of Churches." They extend it especially to the poor, to those persecuted for the faith, as well as to missionaries who are working throughout the world.
