From one of St. Leo's Epiphany sermons, Sermon 33:
A star more brilliant than the other stars arouses wise men that dwell in the far East, and from the brightness of the wondrous light these men, not unskilled in observing such things, appreciate the importance of the sign: this doubtless being brought about in their hearts by Divine inspiration, in order that the mystery of so great a sight might not be hid from them, and, what was an unusual appearance to their eyes, might not be obscure to their minds. In a word they scrupulously set about their duty and provide themselves with such gifts that in worshipping the One they may at the same time show their belief in His threefold function: with gold they honour the Person of a King, with myrrh that of Man, with incense that of God.
Epiphany
I heard the preacher speaking,
and of miracles I heard,
the wine of revelation
from the water of our words.
I heard of men and women
in humility of ways
transfigured to the glory
of the Ancient One of Days
(first river-bathed and lustral
in the waters of the earth,
then drunken, full of Spirit,
with the Wine of heaven's birth),
of wisdom-seeking sages
who had sought the Good by star
and found it with its Mother
where the Jewish peoples are,
the True in swaddled clothing --
thus their wise philosophy
was turned, like wedding-water,
to that wine, epiphany.
