Twenty-First Sunday in Ordinary Time Year A 2023/ Twelfth Sunday after Trinity
God is quite capable of replacing rulers, as he does when he sets Eliakim as vicar general in the Kingdom of Judah, under the Davidic King. Likewise, using similar language, he placed Peter, on the basis of his having been designated by the divine revelation of recognizing Jesus as king (Messiah, Christ) Son of God, as vicar general of his kingdom, a civic community that transcends death itself. Because Peter is in the transcendent sphere Peter's successors rule in this sphere, but the principle is clear: they rule rightly only under the authority of the King but rule with his authority.

Readings
FIRST READING
Isaiah 22:19–23
19 I will thrust you from your office
and pull you down from your station.
20 On that day I will summon my servant
Eliakim, son of Hilkiah;
21 I will clothe him with your robe,
gird him with your sash,
confer on him your authority.
He shall be a father to the inhabitants of Jerusalem,
and to the house of Judah.
22 I will place the key of the House of David on his shoulder;
what he opens, no one will shut,
what he shuts, no one will open.
23 I will fix him as a peg in a firm place,
a seat of honor for his ancestral house;

LORD, your mercy endures forever.
Never forsake the work of your hands!
PSALM
Psalm 138:1–3, 6, 8
1 Of David.
I thank you, Lord, with all my heart;
in the presence of the angels to you I sing.
2 I bow low toward your holy temple;
I praise your name for your mercy and faithfulness.
For you have exalted over all
your name and your promise.
3 On the day I cried out, you answered;
you strengthened my spirit.
6 The LORD is on high, but cares for the lowly
and knows the proud from afar.
8 The LORD is with me to the end.
LORD, your mercy endures forever.
Never forsake the work of your hands!

Romans 11:33–36
33 Oh, the depth of the riches and wisdom and knowledge of God! How inscrutable are his judgments and how unsearchable his ways!
34 “For who has known the mind of the Lord
or who has been his counselor?”
35 “Or who has given him anything
that he may be repaid?”
36 For from him and through him and for him are all things. To him be glory forever. Amen.
GOSPEL ACCLAMATION
Matthew 16:18
18 And so I say to you, you are Peter, and upon this rock I will build my church, and the gates of the netherworld shall not prevail against it.
GOSPEL
Matthew 16:13–20
13 When Jesus went into the region of Caesarea Philippi he asked his disciples, “Who do people say that the Son of Man is?” 14 They replied, “Some say John the Baptist, others Elijah, still others Jeremiah or one of the prophets.” 15 He said to them, “But who do you say that I am?” 16 Simon Peter said in reply, “You are the Messiah, the Son of the living God.” 17 Jesus said to him in reply, “Blessed are you, Simon son of Jonah. For flesh and blood has not revealed this to you, but my heavenly Father. 18 And so I say to you, you are Peter, and upon this rock I will build my church, and the gates of the netherworld shall not prevail against it. 19 I will give you the keys to the kingdom of heaven. Whatever you bind on earth shall be bound in heaven; and whatever you loose on earth shall be loosed in heaven.” 20 Then he strictly ordered his disciples to tell no one that he was the Messiah.
