To God the Father, the Unbegotten, and to the Only-begotten Son, begotten from him, and to the Holy Spirit who proceeds from their essence, to the Three in One substance, be all glory, now and ever, and unto ages of ages. Amen.
The Father, not the Son, is the source of the Holy Spirit.
Writings of a Greek-speaking Syrian bishop named Severian of Gabala:
"Three and One, One and Three: for we profess one essence of the Holy Trinity, in three hypostases of perfect persons. For the person of the Father is not the person of the Son, nor is the person of the Son, or that of the Holy Spirit, the person of the Father, albeit it is, indeed, out of the one very essence of the Father that the Son and the Holy Spirit exist. For the Only-begotten Son, who before all ages exists both from the Father and with the Father, is God with God, and is, the very same, man with men, without any falling away from his divinity, even if he is found to have taken on manhood, nor is he cast down from his first nativity, even if, by his fleshly nativity from a virgin, he has appeared as one born in the flesh. Rather, even while he was in the Virgin’s womb, the heavens and the earth and the whole creation had not been emptied of him.
To God the Father, the Unbegotten, and to the Only-begotten Son, begotten from him [the Ubegotten], and to the Holy Spirit who proceeds† from their essence, to the Three in One substance, be all glory, now and ever, and unto ages of ages. Amen."
