If the Holy Spirit can produce in the Apostles that which the Name of the Father and of the Son produces in the converted pagans, and the Name of Jesus Christ - in the repentant Jews... how, then, can you say that the Spirit, which has the same Energy as the Father and the Son, does not share their Essence?
St. Basil the Great, Against Eunomius, Book 5:
On the Holy Spirit
