Pentecost: The Descent of the Holy Spirit
 
The Feast of Pentecost commemorates the descent of the Holy Spirit upon the disciples. In the Byzantine rite, it is remembered through the lens of the final revelation of the dogma of the Trinity, to which most of the hymns of the holy office refer.
 
The Bible relates: “When Pentecost day came round, they had all met in one room, when suddenly they heard what sounded like a powerful wind from heaven… and something appeared to them like tongues of fire… They were filled with the Holy Spirit, and began to speak foreign languages as the Spirit gave them the gift of speech.” (Acts 2:1-4)
 
Pentecost is also the feast of the foundation of the Church, of the beginning of her mission to the world, and of Christian unity within the diversity of nations, languages, and cultures.

Pentecost Troparion (Tone 8)
Blessed are you You,
O Christ, our God,
for you have given us wise fishermen,
after sending them Your Holy Spirit,
You caught all the world through them,
O Loving Master, glory to You!

In Ukrainian, the feast is called “Zeleni Svyata” or “Green Holidays.” The Church and the homes of the faithful are decorated throughout with green branches and flowers, signifying the new life conferred upon us by the life-creating Spirit.

Pentecost Kondakion (Tone 8)
When once You confused the tongues,
You divided the nations, O Mighty One.
when You bestowed the tongues of fire, You called all to unity,
therefore with one voice,
we glorify the Holy Spirit.

The Sidalen Hymns are sung between the Psalms readings at the morning service (Matins). They interpret the Psalms, applying them to the particular feast celebrated in God’s Word.

1st Sidalen Hymn (Tone 4)
Come, O Faithful, let us celebrate the feast of the Fiftieth Day:
the day which concludes the Feast of feasts;
the day on which the pre-ordained promise is fulfilled;
the day when the Comforter descends upon the earth in tongues of Fire;
the day of the disciples’ enlightenment.
They are revealed as initiated into the heavenly Mysteries,
for truly the light of the Comforter has illumined the world.

In the Second Sidalen, i.e. the Hymns following the 2d Reading from the Book of Psalms, the Spirit’s descent is likened to a fountain whose waters gush down to the earth rather than up from the ground. The flames are compared with the Divine Wind ( literally Spirit) that saved the three holy youths Shadrach, Meshach and Abednego in the fiery furnace of Nebudchadnezaar’s Babylon (cf Book of Daniel, chapter 3.) The youths were condemned to death for worshipping the One True God and refusing to bow down to idols such as the golden statue. It is that same Divine Wind which accompanied the appearance of the Son of God, through Whom the Spirit preserved from burning but brought a cool dew of life.

Second Sidalen Hymn (Tone 4)
The fountain of the Spirit rushes down to earth,
mystically divided into flaming streams, both refreshing and enlightening the Apostles;
the fire became for them a cloud of dew, raining enlightenment upon them.
From them we have received grace by fire and water,
for truly the light of the Comforter has illumined the world.

Extol, O my soul, extol the One God in Trinity of Persons!
