Pentecost is my favorite feast day. Yes, really. So an excerpt from a "long but so worth it" prayer to the wonder of the day and our God, from the Orthodox Church's Symeon the New Theologian:
Come, O true light!
Come, O eternal life!
Come, O hidden mystery!
Come, O indescribable treasure!
Come, O ineffable thing!
Come, O inconceivable person!
Come, O endless delight!
Come, O unsetting light!
Come, O true and fervent expectation
of all those who will be saved!
Come, O rising of those who lie down!
Come, O resurrection of the dead!
Come, O powerful one,
who always creates and re-creates and transforms
by your will alone!
Come, O invisible and totally intangible and untouchable!
I give you thanks that for me
you have become unsetting light
and non-declining sun;
for you who fill the universe with your glory
have nowhere to hide yourself.
No, you have never hidden yourself from anyone
but we are the ones who always hide from you,
by refusing to go to you;
but then, where would you hide,
you who nowhere find the place of your repose?
Why would you hide,
you who do not turn away from a single creature,
who do not reject a single one?
O Master, stay and do not leave me alone,
so that my enemies,
they who are always seeking to devour my soul,
may find you living within me
and that they may take flight,
in defeat, powerless against me,
seeing you, O more powerful than everything,
installed interiorly in the home of my poor soul.
Yea, O Master, just as you remembered me,
when I was in the world
and, in the midst of my ignorance,
you chose me and separated me from this world
and set me before your glorious face,
so now keep me interiorly,
by your dwelling within me,
forever upright, resolute;
that by perpetually seeing you,
I, the corpse, may live;
that by possessing you,
I, the beggar, may always be rich,
richer than kings;
that by eating you and by drinking you,
by putting you on at each moment,
I go from delight to delight
in inexpressible blessings;
for it is You, who are all good and
all glory and all delight
and it is to you,
holy, consubstantial, and life-creating Trinity
that the glory belongs,
you whom all faithful venerate, confess, adore, and serve
in the Father, the Son, and the Holy Spirit,
now and ever and unto the ages of ages. Amen.
