The Holy Trinity – A Strange and Paradoxical Diversity-in-Unity and Unity-in-Diversity

Almighty and everlasting God, you have given to us your servants grace, by the confession of a true faith, to acknowledge the glory of the eternal Trinity, and in the power of your divine Majesty to worship the Unity: Keep us steadfast in this faith and worship, and bring us at last to see you in your one and eternal glory, O Father; who with the Son and the Holy Spirit live and reign, one God, for ever and ever. Amen.

– Collect for the Feast of the Holy Trinity, Book of Common Prayer.

All that the Father is, we see revealed in the Son; all that is the Son’s is the Father’s also; for the whole Son dwells in the Father, and he has the whole Father dwelling in himself…The Son who exists always in the Father can never be separated from him, nor can the Spirit ever be divided from the Son who through the Spirit works all things. He who receives the Father also receives at the same time the Son and the Spirit. It is impossible to envisage any kind of severance or disjunction between them: one cannot think of the Son apart from the Father, nor divide the Spirit from the Son. There is between the three a sharing and a differentiation that are beyond words and understanding. The distinction between the persons does not impair the oneness nor does the shared unity of essence lead to a confusion between the distinctive char­acteristics of the persons. Do not be surprised that we should speak of the Godhead as being at the same time both unified and differentiated. Using riddles, as it were, we envisage a strange and paradoxical diversity-in-unity and unity-in-diversity.

– St. Gregory of Nyssa, quoted in The Orthodox Way, pp. 38-39.

Ἀμήν.
Ἅγιος ὁ Θεός, Ἅγιος Ἰσχυρός, Ἅγιος Ἀθάνατος, ἐλέησον ἡμᾶς.
Ἅγιος ὁ Θεός, Ἅγιος Ἰσχυρός, Ἅγιος Ἀθάνατος, ἐλέησον ἡμᾶς.
Ἅγιος ὁ Θεός, Ἅγιος Ἰσχυρός, Ἅγιος Ἀθάνατος, ἐλέησον ἡμᾶς.
Δόξα Πατρί καὶ Υἱῷ καὶ Ἁγίῳ Πνεύματι.
Καὶ νῦν καὶ ἀεί καὶ εἰς τοὺς αἰώνας τῶν αἰώνων, Ἀμήν.
Ἅγιος Ἀθάνατος, ἐλέησον ἡμᾶς.

Glory to the Father and to the Son and to the Holy Spirit.
Both now and ever and unto ages of ages, Amen.
Holy Immortal, have mercy on us.
