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.
Therefore, with one voice,
we glorify the All-holy Spirit!

 “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.”
