But he rebuked them and would not allow them to speak, because they knew he was the Messiah. (Luke 4: 41)
Jesus left the synagogue and went to the home of Simon. Now Simon’s mother-in-law was suffering from a high fever, and they asked Jesus to help her. So he bent over her and rebuked the fever, and it left her. She got up at once and began to wait on them. At sunset, the people brought to Jesus all who had various kinds of sickness, and laying his hands on each one, he healed them. Moreover, demons came out of many people, shouting, “You are the Son of God!” But he rebuked them and would not allow them to speak, because they knew he was the Messiah. At daybreak, Jesus went out to a solitary place. The people were looking for him and when they came to where he was, they tried to keep him from leaving them. But he said, “I must proclaim the good news of the kingdom of God to the other towns also, because that is why I was sent.” And he kept on preaching in the synagogues of Judea. (Luke 4: 38-44)
Jesus does not want the testimony about His identity to be given away by fallen angels. The angels, in fact, are God’s messengers. We mustn’t add or remove anything from the message entrusted to them. Evil angels, however, are demons. They are liars, and if they tell the truth, they do so in order to confuse our ideas. May we take very seriously that we should never dialogue with Satan, as when he presents himself in extraordinary ways to us. Obviously, we must never do so even when he presents himself in the form of ordinary temptations, so as not to fall into sin.
