The Lord's Prayer is at the center of heated debates about the question of God. "Lead us not into temptation," is how we pray. Is this appropriate? Should the request be changed? Or is it meant to provoke both prayer and thought? The theological controversy runs deep: the biblical testimony must be reinterpreted, the actions of God and the pleas of humans come into focus, liturgical practice is put to the test, and ecumenical relationships are examined. What does "temptation" even mean, and what is divine guidance? How should this negatively phrased request be understood within the entirety of the Lord's Prayer? At its core lies the challenge of rediscovering an ancient prayer for today's people, who seek to express their faith, love, and hope. The Lord's Prayer is the prayer of all prayers. The request regarding temptation is a thorn in the flesh of Christian piety.
