Angel of Light
In his Spiritual Exercises, St. Ignatius says that when the enemy of our human nature finds that he cannot tempt us to break the commandments switches tactics and instead comes to us as an angel of light (2 Cor 11:14) to draw us away from God's love. May God deliver us from the hands of our enemy so that we may "draw water joyfully from the springs of salvation" (Is 12:3).
The Church teaches us to confess that we are not worthy so that we can appreciate the greatness of God's love for us. The Angel of Light insinuates that because we are not worthy, we are unlovable. God is love. God loves us because He is beautiful, not because we are. Our beauty comes from Him and returns to Him. He loves us as we are right now. Most of us are works in progress or unfinished business, but God is not afraid of what our renovation will cost Him. One of His names is Emmanuel, "God with us." He camps with us, as He did with Israel, showing us the way by night and by day. We can't increase His love for us by anything we do. We are not worthy of such love or such a lover, but this is the great good news burning like a fire in our hearts. Love is with us. Love is for us. Love is in us. Love endures.
