“But if it is by the finger of God that I drive out demons, then the kingdom of God has come upon you.” (Luke 11:20)
In commenting on this verse from the Gospel according to Saint Luke from today’s Mass Readings, Cyril of Alexandria writes:
“By the finger of God, he means the Holy Spirit. The Son is called the hand and arm of God the Father because he does all things by the Son, and the Son in a similar way works by the Spirit. Just as the finger is attached to the hand as something not foreign from it but belonging to it by nature, so also the Holy Spirit, by reason of his being equal in substance, is joined in oneness to the Son, although he proceeds from God the Father. The Son does every thing by the consubstantial Spirit. Here he purposely says that by the finger of God he casts out devils, speaking as a man. (Commentary on Luke, Homily 81)”
