The Roman Catholic Church, according to the General Roman Calendar, celebrates the following in Sunday, 2021-04-25:
1 Peter 5:5-14
5Likewise you that are younger be subject to the elders. Clothe yourselves, all of you, with humility toward one another, for "God opposes the proud, but gives grace to the humble." 6Humble yourselves therefore under the mighty hand of God, that in due time he may exalt you. 7Cast all your anxieties on him, for he cares about you. 8Be sober, be watchful. Your adversary the devil prowls around like a roaring lion, seeking some one to devour. 9Resist him, firm in your faith, knowing that the same experience of suffering is required of your brotherhood throughout the world. 10And after you have suffered a little while, the God of all grace, who has called you to his eternal glory in Christ, will himself restore, establish, and strengthen you. 11To him be the dominion for ever and ever. Amen. 12By Silva'nus, a faithful brother as I regard him, I have written briefly to you, exhorting and declaring that this is the true grace of God;stand fast in it. 13She who is at Babylon, who is likewise chosen, sends you greetings;and so does my son Mark. 14Greet one another with the kiss of love. Peace to all of you that are in Christ.
Psalms 89:2-3, 6-7, 16-17
1I will sing of thy steadfast love, O LORD, for ever;with my mouth I will proclaim thy faithfulness to all generations. 2For thy steadfast love was established for ever, thy faithfulness is firm as the heavens. 5Let the heavens praise thy wonders, O LORD, thy faithfulness in the assembly of the holy ones! 6For who in the skies can be compared to the LORD? Who among the heavenly beings is like the LORD, 15Blessed are the people who know the festal shout, who walk, O LORD, in the light of thy countenance, 16who exult in thy name all the day, and extol thy righteousness.
Mark 16:15-20
15And he said to them, "Go into all the world and preach the gospel to the whole creation. 16He who believes and is baptized will be saved;but he who does not believe will be condemned. 17And these signs will accompany those who believe: in my name they will cast out demons;they will speak in new tongues;18they will pick up serpents, and if they drink any deadly thing, it will not hurt them;they will lay their hands on the sick, and they will recover." 19So then the Lord Jesus, after he had spoken to them, was taken up into heaven, and sat down at the right hand of God. 20And they went forth and preached everywhere, while the Lord worked with them and confirmed the message by the signs that attended it. Amen.
Acts 4:8-12
Peter, filled with the Holy Spirit, said:
"Leaders of the people and elders:
If we are being examined today
about a good deed done to a cripple,
namely, by what means he was saved,
then all of you and all the people of Israel should know
that it was in the name of Jesus Christ the Nazorean
whom you crucified, whom God raised from the dead;
in his name this man stands before you healed.
He is the stone rejected by you, the builders,
which has become the cornerstone.
There is no salvation through anyone else,
nor is there any other name under heaven
given to the human race by which we are to be saved."
Ps 118:1, 8-9, 21-23, 26, 28, 29
R. (22)
The stone rejected by the builders has become the cornerstone.
or:
R.Alleluia.
Give thanks to the LORD, for he is good,
for his mercy endures forever.
It is better to take refuge in the LORD
than to trust in man.
It is better to take refuge in the LORD
than to trust in princes.
R.The stone rejected by the builders has become the cornerstone.
or:
R.Alleluia.
I will give thanks to you, for you have answered me
and have been my savior.
The stone which the builders rejected
has become the cornerstone.
By the LORD has this been done;
it is wonderful in our eyes.
R.The stone rejected by the builders has become the cornerstone.
or:
R.Alleluia.
Blessed is he who comes in the name of the LORD;
we bless you from the house of the LORD.
I will give thanks to you, for you have answered me
and have been my savior.
Give thanks to the LORD, for he is good;
for his kindness endures forever.
R.The stone rejected by the builders has become the cornerstone.
or:
R.Alleluia.
1 Jn 3:1-2
Beloved:
See what love the Father has bestowed on us
that we may be called the children of God.
Yet so we are.
The reason the world does not know us
is that it did not know him.
Beloved, we are God's children now;
what we shall be has not yet been revealed.
We do know that when it is revealed we shall be like him,
for we shall see him as he is.
Jn 10:11-18
Jesus said:
"I am the good shepherd.
A good shepherd lays down his life for the sheep.
A hired man, who is not a shepherd
and whose sheep are not his own,
sees a wolf coming and leaves the sheep and runs away,
and the wolf catches and scatters them.
This is because he works for pay and has no concern for the sheep.
I am the good shepherd,
and I know mine and mine know me,
just as the Father knows me and I know the Father;
and I will lay down my life for the sheep.
I have other sheep that do not belong to this fold.
These also I must lead, and they will hear my voice,
and there will be one flock, one shepherd.
This is why the Father loves me,
because I lay down my life in order to take it up again.
No one takes it from me, but I lay it down on my own.
I have power to lay it down, and power to take it up again.
This command I have received from my Father."
