Jesus Christ is begotten of the Father (Psalms 2) – and the Spirit (Who is Seven, Revelation) proceeds from Them. The Father is not begotten, nor does He proceed from the Spirit or the Son

The Holy Spirit—as regards His existence—proceeds (originates) eternally from the Father (St. Gregory Palamas [13th century], Philokalia), and not from the Son. To say that he proceeds from Them is to imply double origin.

The Apostle states:

"the Spirit of truth who proceeds from the Father, He will testify about Me." [St. John 15:26]

St. John of Damascus (8th century desert father) states:

Likewise we believe also in one Holy Spirit, the Lord and Giver of Life: Who proceedeth from the Father and resteth in the Son...proceeding from the Father and communicated through the Son.
(We believe) in one Father, the beginning, and cause of all: begotten of no one: without cause or generation, alone subsisting: creator of all: but Father of one only by nature, His Only-begotten Son and our Lord and God and Saviour Jesus Christ, and Producer of the most Holy Spirit. [Exact Exposition of the Orthodox Faith, Book I, Chapter VIII]

It was not my intent to engage this "hot button" issue on origin but rather to give both the Father and the Son the glory for the Spirit coming to us.

Nevertheless I tell you the truth; It is expedient for you that I go away: for if I go not away, the Comforter will not come unto you; but if I depart, I will send him unto you. - John 16:7

And I beheld, and, lo, in the midst of the throne and of the four beasts, and in the midst of the elders, stood a Lamb as it had been slain, having seven horns and seven eyes, which are the seven Spirits of God sent forth into all the earth. - Revelation 5:6

And my personal favorite which reveals the Trinity:

But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his. - Romans 8:9

To God be the glory!
