Saint John Damascene: "On the Trinity"

Today, December 4, we celebrate the feast day of Saint John Damascene (John of Damascus, 676-749), hymn-writer, defender of icons, and Doctor of the Church. Saint John is considered the last of the four fathers of the Eastern Church. He devoted himself to religious poetry, theological arguments in defense of Church doctrine, and refutation of heresies. A prolific writer, many of his works remain, including beautiful canons on the Assumption of Our Blessed Mother, Easter, and the Ascension. His eloquent defense of icons and Christian art earned him the title, “The Doctor of Christian Art.”


A prolific writer, Saint John wrote a text entitled “On Heresies.” Below, an excerpt on the Holy Trinity.

We believe in Father and Son and Holy Ghost;
one Godhead in three hypostases;
one will, one operation, alike in three persons;
wisdom incorporeal, uncreated, immortal, incomprehensible,
without beginning, unmoved, unaffected, without quantity,
without quality, ineffable, immutable, unchangeable, uncontained,
equal in glory, equal in power, equal in majesty, equal in might, equal in nature,
exceedingly substantial, exceedingly good,
thrice radiant, thrice bright, thrice brilliant.

Light is the Father, Light the Son, Light the Holy Ghost;
Wisdom the Father, Wisdom the Son, Wisdom the Holy Ghost;
one God and not three Gods;
one Lord the Holy Trinity discovered in three hypostases.

Father is the Father, and unbegotten;
Son is the Son, begotten and not unbegotten, for He is from the Father;
Holy Ghost, not begotten but proceeding, for He is from the Father.

There is nothing created, nothing of the first and second order, nothing lord and servant;
but there is unity and trinity
- there was, there is, and there shall be forever -
which is perceived and adored by faith -
by faith, not by inquiry, nor by searching out, nor by visible manifestation;
for the more He is sought out, the more He is unknown, and the more He is investigated, the more He is hidden.

And so, let the faithful adore God with a mind that is not overcurious. And believe that He is God in three hypostases, although the manner in which He is so is beyond manner, for God is incomprehensible. Do not ask how the Trinity is Trinity, for the Trinity is inscrutable.

But, if you are curious about God, first tell me of yourself and the things that pertain to you. How does your soul have existence? How is your mind set in motion? How do you produce your mental concepts? How is it that you are both mortal and immortal? But, if you are ignorant of these things which are within you, then why do you not shudder at the thought of investigating the sublime things of heaven?

Think of the Father as a spring of life begetting the Son like a river and the Holy Ghost like a sea, for the spring and the river and sea are all one nature.

Think of the Father as a root, and of the Son as a branch, and the Spirit as a fruit, for the substance in these three is one.

The Father is a sun with the Son as rays and the Holy Ghost as heat.

The Holy Trinity transcends by far every similitude and figure. So, when you hear of an offspring of the Father, do not think of a corporeal offspring. And when you hear that there is a Word, do not suppose Him to be a corporeal word. And when you hear of the Spirit of God, do not think of wind and breath. Rather, hold you persuasion with a simple faith alone. For the concept of the Creator is arrived at by analogy from His creatures.

Be persuaded, moreover, that the incarnate dispensation of the Son of God was begotten ineffably without seed of the blessed Virgin, believing Him to be without confusion and without change both God and man, who for your sake worked all the dispensation. And to Him by good works give worship and adoration, and venerate and revere the most holy Mother of God and ever-virgin Mary as true Mother of God, and all the saints as His attendants.

Doing thus, you will be a right worshiper of the holy and undivided Trinity, Father and Son and Holy Ghost, of the one Godhead, to whom be glory and honor and adoration forever and ever. Amen
