Council of Constantinople (360) - Wikipedia, the free encyclopedia
But since the term ousia [substance or essence], which was used by the fathers in a very simple and intelligible sense, but not being understood by the people, has been a cause of offense, we have thought proper to reject it, as it is not contained even in the sacred writings; and that no mention of it should be made in future, inasmuch as the holy Scriptures have nowhere mentioned the substance of the Father and of the Son. Nor ought the "subsistence" of the Father, and of the Son, and of the Holy Spirit to be even named.
Not even to be named... yet name they did. Priests...
Just because a bunch of theologians gathered and agreed on something, does not prove the veracity of their statement.
The truth is that the Bible does say that God is spirit and the Paraclete is called the Spirit of Truth. With Jesus the appellation is a bit more subtle. Can spirit be considered a substance? I would deem it so since a substance is simply something that exists.
John 4:24 God is a Spirit: and they that worship him must worship in spirit and truth.
John 14:16 And I will pray the Father, and he shall give you another Comforter (Paraclete), that he may be with you for ever, 17 even the Spirit of truth
Luke 1:35 And the angel answered and said unto her, The Holy Spirit shall come upon thee, and the power of the Most High shall overshadow thee: wherefore also the holy thing which is begotten shall be called the Son of God.
