Today is Pentecost Sunday—the birth of Christianity in the world.
Acts 1: 4 - 5
On one occasion, while he was eating with them, he gave them this command: “Do not leave Jerusalem, but wait for the gift my Father promised, which you have heard me speak about. For John baptized with water, but in a few days you will be baptized with the Holy Spirit.”
After Jesus Christ ascended into heaven, the apostles and disciples waited for the nine days in an upper room in Jerusalem. Praying and waiting for a sign from God, for the paraclete—the advocate, intercessor, consoler, comforter, helper—as spoken by Jesus.
Acts 2: 1 - 4
When the day of Pentecost came, they were all together in one place.Suddenly a sound like the blowing of a violent wind came from heaven and filled the whole house where they were sitting.They saw what seemed to be tongues of fire that separated and came to rest on each of them. All of them were filled with the Holy Spirit and began to speak in other tongues as the Spirit enabled them.
And then the apostles and the disciples left the upper room, and Peter filled with courage and boldness from the Holy Spirit spoke to the crowd outside.
Acts 2: 14 - 47
Then Peter stood up with the Eleven, raised his voice and addressed the crowd: “Fellow Jews and all of you who live in Jerusalem, let me explain this to you; listen carefully to what I say. These people are not drunk, as you suppose. It’s only nine in the morning! No, this is what was spoken by the prophet Joel:
“ ‘In the last days, God says,
I will pour out my Spirit on all people.
Your sons and daughters will prophesy,
your young men will see visions,
your old men will dream dreams.
Even on my servants, both men and women,
I will pour out my Spirit in those days,
and they will prophesy.
I will show wonders in the heavens above
and signs on the earth below,
blood and fire and billows of smoke.
The sun will be turned to darkness
and the moon to blood
before the coming of the great and glorious day of the Lord.
And everyone who calls
on the name of the Lord will be saved.’
“Fellow Israelites, listen to this: Jesus of Nazareth was a man accredited by God to you by miracles, wonders and signs, which God did among you through him, as you yourselves know. This man was handed over to you by God’s deliberate plan and foreknowledge; and you, with the help of wicked men, put him to death by nailing him to the cross.But God raised him from the dead, freeing him from the agony of death, because it was impossible for death to keep its hold on him. David said about him:
“ ‘I saw the Lord always before me.
Because he is at my right hand,
I will not be shaken.
Therefore my heart is glad and my tongue rejoices;
my body also will rest in hope,
because you will not abandon me to the realm of the dead,
you will not let your holy one see decay.
You have made known to me the paths of life;
you will fill me with joy in your presence.’
“Fellow Israelites, I can tell you confidently that the patriarch David died and was buried, and his tomb is here to this day. But he was a prophet and knew that God had promised him on oath that he would place one of his descendants on his throne.Seeing what was to come, he spoke of the resurrection of the Messiah, that he was not abandoned to the realm of the dead, nor did his body see decay. God has raised this Jesus to life, and we are all witnesses of it. Exalted to the right hand of God, he has received from the Father the promised Holy Spirit and has poured out what you now see and hear. For David did not ascend to heaven, and yet he said,
“ ‘The Lord said to my Lord:
“Sit at my right hand
until I make your enemies
a footstool for your feet.” ’
“Therefore let all Israel be assured of this: God has made this Jesus, whom you crucified, both Lord and Messiah.”
When the people heard this, they were cut to the heart and said to Peter and the other apostles, “Brothers, what shall we do?”
Peter replied, “Repent and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of your sins. And you will receive the gift of the Holy Spirit.The promise is for you and your children and for all who are far off—for all whom the Lord our God will call.”
With many other words he warned them; and he pleaded with them, “Save yourselves from this corrupt generation.” Those who accepted his message were baptized, and about three thousand were added to their number that day.
The Fellowship of the Believers
They devoted themselves to the apostles’ teaching and to fellowship, to the breaking of bread and to prayer. Everyone was filled with awe at the many wonders and signs performed by the apostles. All the believers were together and had everything in common.They sold property and possessions to give to anyone who had need. Every day they continued to meet together in the temple courts.They broke bread in their homes and ate together with glad and sincere hearts, praising God and enjoying the favor of all the people. And the Lord added to their number daily those who were being saved.
And Christianity was born and grew as the Holy Spirit filled the hearts of Christians with faith, hope, peace, and love.
But what would have happened if the apostles and disciples had never left the upper room after they received the Holy Spirit? What if they just continued to pray and wait to see what else God would do? What if they never responded to the promptings and instructions of the Holy Spirit?
What would Christianity look like? Would we even have Christianity?
As Children of God, we are also filled with the Holy Spirit at our baptism. We also receive the gifts and fruit of the Holy Spirit. God also gives us free will so that our Christianity is not forced upon us but comes from our deepest desire to do His will—to proclaim the Good News through our words and works.
We are ALL called to be apostles and disciples NOW.
So, what are we waiting for?
Come Holy Spirit, fill the hearts of your faithful and kindle in them the fire of your love. Send forth your spirit and they shall be created. And you shall renew the face of the earth.
