The Roman Catholic Church, according to the General Roman Calendar, celebrates the following in Sunday, 2023-05-14:
Acts 1:15-17, 20-26
15In those days Peter stood up among the brethren (the company of persons was in all about a hundred and twenty), and said, 16"Brethren, the scripture had to be fulfilled, which the Holy Spirit spoke beforehand by the mouth of David, concerning Judas who was guide to those who arrested Jesus. 17For he was numbered among us, and was allotted his share in this ministry. 20For it is written in the book of Psalms, `Let his habitation become desolate, and let there be no one to live in it'; and `His office let another take.' 21So one of the men who have accompanied us during all the time that the Lord Jesus went in and out among us, 22beginning from the baptism of John until the day when he was taken up from us -- one of these men must become with us a witness to his resurrection." 23And they put forward two, Joseph called Barsab'bas, who was surnamed Justus, and Matthi'as. 24And they prayed and said, "Lord, who knowest the hearts of all men, show which one of these two thou hast chosen 25to take the place in this ministry and apostleship from which Judas turned aside, to go to his own place." 26And they cast lots for them, and the lot fell on Matthi'as; and he was enrolled with the eleven apostles.
Psalms 113:1-8
1Praise the LORD! Praise, O servants of the LORD, praise the name of the LORD! 2Blessed be the name of the LORD from this time forth and for evermore! 3From the rising of the sun to its setting the name of the LORD is to be praised! 4The LORD is high above all nations, and his glory above the heavens! 5Who is like the LORD our God, who is seated on high, 6who looks far down upon the heavens and the earth? 7He raises the poor from the dust, and lifts the needy from the ash heap, 8to make them sit with princes, with the princes of his people.
John 15:9-17
9As the Father has loved me, so have I loved you; abide in my love. 10If you keep my commandments, you will abide in my love, just as I have kept my Father's commandments and abide in his love. 11These things I have spoken to you, that my joy may be in you, and that your joy may be full. 12"This is my commandment, that you love one another as I have loved you. 13Greater love has no man than this, that a man lay down his life for his friends. 14You are my friends if you do what I command you. 15No longer do I call you servants, for the servant does not know what his master is doing; but I have called you friends, for all that I have heard from my Father I have made known to you. 16You did not choose me, but I chose you and appointed you that you should go and bear fruit and that your fruit should abide; so that whatever you ask the Father in my name, he may give it to you. 17This I command you, to love one another.
acts 8:5-8, 14-17
Philip went down to the city of Samaria
and proclaimed the Christ to them.
With one accord, the crowds paid attention to what was said by Philip
when they heard it and saw the signs he was doing.
For unclean spirits, crying out in a loud voice,
came out of many possessed people,
and many paralyzed or crippled people were cured.
There was great joy in that city.
Now when the apostles in Jerusalem
heard that Samaria had accepted the word of God,
they sent them Peter and John,
who went down and prayed for them,
that they might receive the Holy Spirit,
for it had not yet fallen upon any of them;
they had only been baptized in the name of the Lord Jesus.
Then they laid hands on them
and they received the Holy Spirit.

1 pt 3:15-18
Beloved:
Sanctify Christ as Lord in your hearts.
Always be ready to give an explanation
to anyone who asks you for a reason for your hope,
but do it with gentleness and reverence,
keeping your conscience clear,
so that, when you are maligned,
those who defame your good conduct in Christ
may themselves be put to shame.
For it is better to suffer for doing good,
if that be the will of God, than for doing evil.
For Christ also suffered for sins once,
the righteous for the sake of the unrighteous,
that he might lead you to God.
Put to death in the flesh,
he was brought to life in the Spirit.
jn 14:15-21
Jesus said to his disciples:
"If you love me, you will keep my commandments.
And I will ask the Father,
and he will give you another Advocate to be with you always,
the Spirit of truth, whom the world cannot accept,
because it neither sees nor knows him.
But you know him, because he remains with you,
and will be in you.
I will not leave you orphans; I will come to you.
In a little while the world will no longer see me,
but you will see me, because I live and you will live.
On that day you will realize that I am in my Father
and you are in me and I in you.
Whoever has my commandments and observes them
is the one who loves me.
And whoever loves me will be loved by my Father,
and I will love him and reveal myself to him."
