Acts 2:4

"And they were all filled with the Holy Spirit. And they began to speak in various languages, just as the Holy Spirit bestowed eloquence to them."

Pentecost commemorates the Descent of the Holy Spirit upon the Apostles, which took place fifty days after the Resurrection of Christ, on the ancient Jewish festival called by titles such as

1. The Feast of Weeks (Exodus 34:22; Deuteronomy 16:10; 2 Chronicles 8:13)

2. The Feast of Harvest of the First Fruits (Exodus 23:16)

3. The Day of First Fruits (Numbers 28:26)

Pentecost in the Book of Acts, Chapter 2,

“And when the days of Pentecost were completed, they were all together in the same place. And suddenly, there came a sound from heaven, like that of a wind approaching violently, and it filled the entire house where they were sitting. And there appeared to them separate tongues, as if of fire, which settled upon each one of them. And they were all filled with the Holy Spirit. And they began to speak in various languages, just as the Holy Spirit bestowed eloquence to them.”

This passage describes two elemental forces of nature—Wind and Fire.

We know that the Holy Spirit is a Person of the Holy Trinity and not a force of nature.

Therefore, let us cease to think that the Greatest and Most Powerful Person is similar to either a small flame or violent wind.

Who then is this Person and how do our human minds grasp his Holy Presence?

Answer:
Sound from heaven; not wind
Separate tongues; not fire

Wind and fire were used as analogies.

Spirit (most important)

To focus on the purpose and not on the outcome, the purpose of the Holy Spirit at Pentecost was to empower those present to speak in various languages so that they could spread the Good News about the Kingdom of God throughout the earth. This had the best outcome known to humankind—the Holy Catholic Church. 

However, if we focus on the outcome in that room then imagine…

Everyone’s hair is on fire, and a violent wind is trying to extinguish it.

Or

A violent wind is blowing … wait a second, did you try lighting your candle in a mild wind—remember the Easter Night Vigil Holy Mass Celebration?

Yes, it does not continue, it goes out before the priest finishes the required rites. Therefore, what flame can remain in a violent wind?

Rather than thinking of things that are below such as wind and fire, let Pentecost be a time for us to focus on the purpose of the Holy Spirit, which I think came through the Sound from heaven, to speak in various languages and to spread the Gospel to all Humankind.

But how can we?

… just as the Holy Spirit bestowed eloquence to them.
