John Chrysostom
Why did Paul silence the spirit that declared, ‘These men are servants of the Most High God, who proclaim to us the way of salvation’ (Acts 16:17)? Additionally, why did Christ restrain the demons from speaking? In the former instance with the apostle, it was appropriate to do so because the spirit was capable of demonstrating signs. In contrast, during Christ's ministry, there was no need for such manifestations, as He proclaimed His own identity directly, while the demons did not honor Him. When the speaker was not an image, he was allowed to speak; similarly, God allowed Balaam to utter blessings without prohibition (Num. 23).
