Book Excerpts

  1. From Fr. John Behr, Mystery Of Christ (pg. 36) [Behr, J. (2006). The Mystery of Christ: Life in Death. St Vladimirs Seminary Pr.]
How do we come to believe in Father, Son, and Holy Spirit as One True God who is one substance but three persons? We must start at the same place that the Apostles started. We must start with contemplating the crucified and exalted Christ. As Fr John Behr says, “theology proper begins and ends with the contemplation of the crucified and exalted Christ – the one Lord Jesus Christ, the very Word of God.”

In order to help our children grow in the Orthodox Faith in North America, a decision was made to standardize all materials to the Orthodox Study Bible (DSWA Kalpana DSWA/C/016/2010, October 28, 2010). Please continue to pray and support the development of a fully approved translation based on the Peshitta, and our textbooks will educate on the various translations and historic development of Scripture.

  • [Genesis 1:1-2]

    In the beginning God made heaven and earth. The earth was invisible and unfinished; and darkness was over the deep. The Spirit of God was hovering over the face of the water.

  • [Mathew 3:16-17]

    When He had been baptized, Jesus came up immediately from the water; and behold, the heavens were opened to Him, and He saw the Spirit of God descending like a dove and alighting upon Him. And suddenly a voice came from heaven, saying, “This is My beloved Son, in whom I am well pleased.”

  • [Luke 3:21-22]

    When all the people were baptized, it came to pass that Jesus also was baptized; and while He prayed, the heaven was opened. And the Holy Spirit descended in bodily form like a dove upon Him, and a voice came from heaven which said, “You are My beloved Son; in You I am well pleased.”

  • [John 1:14]

    And the Word became flesh and dwelt among us, and we beheld His glory, the glory as of the only begotten of the Father, full of grace and truth.

  • [John 10:30]

    I and My Father are one.

  • [John 14:9-11]

    Jesus said to him, “Have I been with you so long, and yet you have not known Me, Philip? He who has seen Me has seen the Father; so how can you say, ‘Show us the Father’? Do you not believe that I am in the Father, and the Father in Me? The words that I speak to you I do not speak on My own authority; but the Father who dwells in Me does the works. Believe Me that I am in the Father and the Father in Me, or else believe Me for the sake of the works themselves.

  • [John 14:16-17]

    And I will pray the Father, and He will give you another Helper, that He may abide with you forever— the Spirit of truth, whom the world cannot receive, because it neither sees Him nor knows Him; but you know Him, for He dwells with you and will be in you.

  • [Ephesians 5:31-32]

    “For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh.” This is a great mystery, but I speak concerning Christ and the church.

  • [2 Corinthians 13:14]

    The grace of the Lord Jesus Christ, and the love of God, and the communion of the Holy Spirit be with you all. Amen.

  • [1 John 5:7-8]

    For there are three that bear witness in heaven: the Father, the Word, and the Holy Spirit; and these three are one. And there are three that bear witness on earth:a the Spirit, the water, and the blood; and these three agree as one.

  • [1 Peter 1:1-2]

    Peter, an apostle of Jesus Christ, To the pilgrims of the Dispersion in Pontus, Galatia, Cappadocia, Asia, and Bithynia, elect according to the foreknowledge of God the Father, in sanctification of the Spirit, for obedience and sprinkling of the blood of Jesus Christ: Grace to you and peace be multiplied.

Liturgical Resources

The Ministry of Liturgical Resource Development (LRD) was created in July of 2015 (DSWA Kalpana DSWA/C/10/2015, July 24,2015) to promote the translation, versification, and publication of vital English liturgical resources. Today most of our Sacramental offices are available and the "Service Book of the Holy Qurbono" and "Shehimo: Book of Common Prayer" are available in print. Wherever possible references will be made using LRD resources given the easy access to these materials to the faithful in North America.

O Holy Father, guard us by Your Sacred Name,
O Son of God, our Savior, protect us with Your victorious Cross †.

Promion and Sedro

  • The Sacrament of Holy Matrimony - Prumiyon (LRD, pg. 22)
Glory to the Self-existent One, Who existed, exists and will exist forever; to the Eternal Word, Whom the angels above His throne, worship; to the Great and Exalted One, Who had pity on us all because of His abundant mercy; to the One Who turned our fallen human race back to Him and Who by His love, made our nature, which had alienated itself from Him, worthy of drawing near to Him; to the One Whom both philosophers and skeptics have no choice but to worship, for even they are unable to question or examine His Being; to the One Who plaits jeweled crowns for the princes; to One Who when He looses, everything remains loosed and when He binds, everything remains bound; to the Majestic One, Who confers crowns of joy to the bridegroom and the bride; to Him belongs glory and honor at this time of the blessing of the crowns of his servants and at all festivals, times, seasons, hours and all the days of our lives, forever.

  • The Feast of Pentecost - Promeon (LRD, pg. 41)
Glory to Him who is invisible, mysterious and beyond human comprehension, thought and mind. He, Who is self-existent, self sufficient, Maker and Author of all things visible and invisible and has no beginning and will continue with no end. The eternal, everlasting and the incomprehensible one true God, one nature, one authority and one will of the Father, the Son and the Holy Spirit.
There is not in Him a name without a Person and no Person is younger or older than the other Person, neither is there any transformation or alteration of one Person to another in greatness and smallness. No name or Person is younger or separated from the Divine Substance. Whenever the Father is mentioned, the Son and the Spirit are of Him, and when the Son is mentioned, the Father and the Spirit are acknowledged in Him, and when the Spirit is mentioned the Father and the Son are included.
The Father begets and is not begotten. The Son is begotten and does not beget. The Holy Spirit proceeds from the Father and takes from the Son and is consubstantial and co-essential with the Father. To Him be glory, honor and dominion at this time of the celebration of Pentecost and at all festivals, times, hours, seasons and through all the days of our life forever.


Patristic Quotes

  • [St. Gregory of Nazianzus] “This I give you to share, and to defend all your life, the one Godhead and power, found in the three in unity”
  • [St. Gregory of Nazianzus] “No sooner do I conceive of the one than I am illumined by the splendor of the three; no sooner do I distinguish them than I am carried back to the one.”
  • [St. Gregory of Nazianzus] "When did these come into being? They are above all "When." But, if I am to speak with something more of boldness,--when the Father did. And when did the Father come into being. There never was a time when He was not. And the same thing is true of the Son and the Holy Ghost. Ask me again, and again I will answer you, When was the Son begotten? When the Father was not begotten. And when did the Holy Ghost proceed? When the Son was, not proceeding but, begotten--beyond the sphere of time, and above the grasp of reason; although we cannot set forth that which is above time, if we avoid as we desire any expression which conveys the idea of time (Theological Orations III.3)."
  • [St. Gregory of Nazianzus] "To us there is One God, for the Godhead is One, and all that proceedeth from Him is referred to One, though we believe in Three Persons. For one is not more and another less God; nor is One before and another after; nor are They divided in will or parted in power; nor can you find here any of the qualities of divisible things; but the Godhead is, to speak concisely, undivided in separate Persons; and there is one mingling of Light, as it were of three suns joined to each other. When then we look at the Godhead, or the First Cause, or the Monarchia, that which we conceive is One; but when we look at the Persons in Whom the Godhead dwells, and at Those Who timelessly and with equal glory have their Being [in] the First Cause--there are Three Whom we worship (Theological Orations V.14)."
  • [St. Gregory of Nazianzus] "This, then, is my position with regard to these things, and I hope it may be always my position, and that of whosoever is dear to me; to worship God the Father, God the Son, and God the Holy Ghost, Three Persons, One Godhead, undivided in honour and glory and substance and kingdom (Theological Orations V.28)."

Other Quotes

  • [HG Geevarghese Mar Osthathios] “The basis of our Christian theology is in the Holy Trinity"
  • [Vladimir Lossky] "The Trinity is for the Orthodox church, the unshakeable foundation of all religious thought, of all piety, of all spiritual life, of all experience."
