Excerpt from Great Vespers with Litiya:
Today Elizabeth rejoices as she gives birth
to the end of the prophets and the beginning of the apostles,
the earthly angel and the heavenly man,
the voice of the Word, the soldier and forerunner of Christ,
who leaped for joy beforehand because of the Promised One
and who preached before the birth of the Sun of Justice.
In his old age Zechariah is amazed,
having cast aside the muteness imposed as a punishment.
As the father of the Voice, he prophesies most splendidly:
And you, O child, shall be called the prophet of the Most High,
and you shall go before Him to prepare the way.
Therefore, O angel, prophet, apostle, and soldier,
forerunner, baptizer, preacher of penance, and guide,
as the voice of the light of the Word,
pray unceasingly for us who faithfully keep your memory.
