In the prehistoric times, mankind decided they would force their way into heaven. The biblical narrative explains they built a large tower with the intention of walking right into heaven. Their plan was destroyed when they found themselves speaking in diverse tongues and no longer able to understand each other.
Pentecost, which was celebrated today in the Orthodox Church, could be considered Babel upside down. The Holy Spirit descended among us and the diverse tongues that once divided mankind acted to unite.
Now, we no longer build towers to reach into the heavens because the heavens have come sweeping down into our world.
As one Kondak goes,
“When the Most High came down and confused the tongues,
He divided the nations, but when He distributed the tongues of fire, He called all to unity, and with one voice we glorify the Most Holy Spirit.”
