Day Two of Passover. As aJewishChristian I think of the Shema Prayer—“Hear, O Israel, the Lord our God, the Lord is One.” It’s also Wednesday of Holy Week, the beginning of the end of Lent. As a JewishChristianI think of all the ones in this tradition:Credo in unum Deum, “I believe in One God”; “The Church’s one Foundation is Jesus Christ, Her Lord. . . .”; even the contrast between the Devil as “legion,” many, and God as one. And as a Sufi, I begin my walking meditation by moving in a circle, my eyes fixed on the horizon.
