The best response

Albert Mohler finds an approach to Halloween suggested by the fact that this is also Reformation Day:

The coming of Halloween is a good time for Christians to remember that evil spirits are real and that the Devil will seize every opportunity to trumpet his own celebrity. Perhaps the best response to the Devil at Halloween is that offered by Martin Luther, the great Reformer: "The best way to drive out the devil, if he will not yield to texts of Scripture, is to jeer and flout him for he cannot bear scorn."

On October 31, 1517, Martin Luther began the Reformation with a declaration that the church must be recalled to the authority of God's Word and the purity of biblical doctrine. With this in mind, the best Christian response to Halloween might be to scorn the Devil and then pray for the Reformation of Christ's church on earth. Let's put the dark side on the defensive.

That passage is at the end of a very good essay about the origins of Halloween and Christian reactions to it. Read it all.
