On the Words of the Divine Jesus Prayer

by St Mark of Ephesus


Commemoration of St Aquila the Apostle among the 70

Anno Domini 2023, July 14

HOW MUCH more power is possessed by the Prayer “Lord Jesus Christ, Son of God, have mercy on me,” and what gifts it confers on those who practice it, and to what spiritual state it leads them, it lies beyond our power to say. The words which constitute this Prayer were initially formulated by our Holy Fathers. They did not, however, themselves make up these words, but took them originally from Holy Scripture and from the chief disciples of Christ. Or, to express it better, they received them as an inheritance from the Fathers who were before them, and passed this inheritance on to us. Thus from this alone, for those who have not learnt it from experience, it is clear that this holy Prayer is something divinely inspired and is as it were a sacred oracle. For we believe that Christ spoke through the holy Apostles, and that everything entrusted to them—either to repeat verbally or to write down—constitutes the divine oracles, spiritual revelations and the words of God.


Thus St. Paul, addressing us from the third heaven (cf. 1 Cor. 12:2), states: “No one can say ‘Lord Jesus’ except through the Holy Spirit” (1 Cor. 12:3). By using the negative words “no one,” St. Paul admirably reveals that the invocation of the Lord Jesus is very sublime and beyond the power of most people. In addition, St. John the Theologian, who speaks of things spiritual “with a voice of thunder,” begins with one of the words that St. Paul provides, and then gives the continuation of the Prayer, as follows: “Every spirit that confesses Jesus Christ is come in the flesh is from God” (1 John 4:2). Here certainly he makes an affirmative statement, but attributes, as does St. Paul, the invocation and the confession of Jesus Christ to the grace of the Holy Spirit. Then, thirdly, St. Peter, the chief of the Apostles, completes the Prayer. Thus, when our Lord asked His disciples, “Whom do you say that I am?” St. Peter, as usual in his enthusiasm forestalling the other disciples, answered, “Thou art the Christ, the Son of the living God,” this being revealed to him, as the Savior Himself testified, by the same heavenly Father or—which is the same thing—by the Holy Spirit (cf. Matt. 16:15-17).


Observe, then, how these three holy Apostles follow one another as though in a circle, the one taking up from the other the divine words in such a manner that the last word in the statement of the first is used as the first word in the statement of the second, and the last word in the second is used as the first word in the third. Thus St. Paul says, “Lord Jesus”; St. John, “Jesus Christ”; and St. Peter, “Christ, Son of God.” Thus the last links up with the first as though in a circle, as we said; for there is no difference in saying “Lord” and “Son of God,” since both these titles reveal the divinity of the only-begotten Son of God and affirm that He is of one essence and of equal rank with the Father.


In this manner the blessed Apostles taught us to invoke our Lord Jesus Christ the Son of God and to confess Him through the Holy Spirit; and since these Apostles are three, they are entirely to be trusted, for according to Holy Scripture every statement confirmed by three witnesses is valid (cf. Matt. 18:16; 2 Cor. 13:1; 1 Tim. 5:19).

"What is it that has ordered the things of heaven and those of earth, the things which move through the air and those which move in the water; nay, rather the things which proceeded them: heaven and earth and the natures of fire and water? What is it that combined and arranged them...set them into motion and put them on their unceasing and unhindered course?..But who is the architect of these things? Or did not he who made them also bring them into being? We shall certainly not attribute such power to spontaneity." On the Orthodox Faith, Chapter 3 This comes after St. John of Damascus sets out to delineate between the created and the uncreated, a fact which, while at the core of existence, seems for him to be, for this very reason, the simplest to believe. Everything but God is created and, thus, susceptible to change. This means people, but this also means demons, angels, the rest of the created order across the entire cosmos. Everything is vulnerable to unrest. Except for God. If you have ever tried to explain the Holy Trinity to a child for the first time, maybe you have felt as I have the weightier, inexpressible side of God's unchangeability: how do I possibly communicate this essential fact to the person in front of me? (This is usually when my faint stutter starts to pop up again.) I like that here, like St. Patrick reaching for a three-leaf clover, St. John brings us back to earth to better understand the cosmos. Fire and water are no less mysteries than heaven and earth. And yet here we are, cooking and washing, eating and drinking, filled and sustained on what we can neither fully explain nor claim to have created. Only God is unchanging. Vice versa, God is the only constant we need. Maybe the rest is better left unsaid. LUKE TAYLOR GILSTRAP is Vice President of the Board of Directors for Eighth Day Institute.

"Now, one who would speak or hear about God should know beyond any doubt that in what concerns theology and the Incarnation not all things are inexpressible and not all are capable of expression, and neither are all things unknowable nor are they all knowable. That which can be known is one thing, whereas that which can be said is another, just as it is one thing to speak and another to know. Furthermore, many of those things about God which are not clearly perceived cannot be fittingly described, so that we are obliged to express in human terms things which transcend the human order. Thus, for example, in speaking about God we attribute to Him sleep, anger, indifference, hands and feet, and the like." On the Orthodox Faith, Chapter 2 When I was studying Fiction in graduate school, one of the first methods I learned to really situate the reader in the story you were about to tell them was disorientation; if you wanted to ground them in one story, first you had pull the rug out from under their feet. So it's fitting that in the beginning of St. John Damascene's On the Orthodox Faith, before rebuilding our foundation, he first puts us squarely in limbo, seesawing back and forth between certainty and uncertainty. To paraphrase, there is no doubt (certainty) that about God some things can be expressed...but not all things (uncertainty). Some things about God are truly knowable (certainty), but some are unknowable (uncertainty). Oh, and while we're speaking about God (certainty), let's admit there's a gap, too, between what we say and what we know (uncertainty). My favorite line in this spiraling excerpt, "...it is one thing to speak, and another to know," takes me back to the final lines in Wendell Berry's poem, "How to Be a Poet," which he wrote primarily as a reminder to himself: Accept what comes from silence. Make the best you can of it. Of the little words that come out of the silence, like prayers prayed back to the one who prays, make a poem that does not disturb the silence from which it came. Wherever your preferences fall on the cataphatic or apophatic spectrum of theology (whether you lean more toward what we can say about God or what we cannot), Berry's poem, I think, would nod along with St. John: before we say too much, let our words be preserved by the silence from which they came. I'm thinking of the silence, that filling, restorative quiet I feel when I step into a cathedral or in some of my favorite moments with my kids in the early hours. Even before praying, can we hear the One already praying in us? ​​​​​​​Let's start there. LUKE TAYLOR GILSTRAP is Vice President of the Board of Directors for Eighth Day Institute.
