And unclean spirits, when they saw him, fell down before him, and cried, saying, You are the Son of God.
All Commentaries on Mark 3:11 Go To Mark 3
George Leo Haydock
AD 1849
The unclean spirits being obliged by the Divine Power, not only to come and worship, but also to declare his majesty, exclaimed: Thou art the Son of God. How astonishing then is the blindness of the Arians, who even after his resurrection denied him to be the Son of God, whom the devils confessed as such when clothed with human nature. But it is certain that not only the devils, but the infirm that were healed, and the apostles themselves were forbidden, as well as the unclean spirits, to proclaim his divinity; lest the passion and death of Christ might be on that account deferred. (Ven. Bede)
