The Roman Catholic Church, according to the General Roman Calendar, celebrates the following in Sunday, 2017-05-21:
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."
