 Why did Jesus ask for Legion's name? Obviously, he already knew the name, so this could have simply been a demonstration of his power to show that he had the authority to drive out even a whole legion of demons instantly. Another thing to consider is the fact that in certain parts of the ancient world, it was believed that to learn someone's name was to gain power over them. The fact that Jesus didn't speak the name of the demon even after being given the name could have been him demonstrating, I know your name, but I don't need to use it to have authority over you. Truly, the only name you need to know when confronting a demonic power is the name of Jesus. To conclude that Jesus would have been unable to cast out the Legion of Demons without knowing its name, would be to greatly underestimate the power of the Holy Spirit and to greatly overestimate the power of the demonic.
