The answer
It is a sentence which is used to confess the divinity of the Holy Spirit, in response to the heresy of Macedonius, who claimed that the Holy Spirit is a creature like the angels, and come forth from the Father and the Son (in time). Therefore, He is not eternal.
The meaning of this article can be made clear through two points:
Firstly: The Holy Spirit is called, “the Giver of Life,” because He gives the true life to every living being, i.e. He is the One Who grants the breath of life (Gen. 2:7).
Secondly: He is the One Who bestows upon us the life of grace, i.e. He is the only means of the sanctification of the believers (Rom. 8:13; 2 Pet. 1:21), as in the Seven Mysteries of the Church.
