As an introduction to this series, today we face the reality of spiritual warfare. This is no mere ideology or intellectualized thinking. The demonic, the principalities, the powers, the rulers of this dark age, and hosts of wickedness in the heavenly places (as St. Paul says in Ephesians 6); they are all real and they all war against the Christian soul. St. Peter tells us that we must live sober and vigilant lives in our war that overcomes them all. Today the purpose of this series and our approach to learning the strategies of our enemy are revealed so that we may all the more recognize them; so that we may live in Christ's victory over them.
