The one and only test of a valid religious idea, doctrinal statement, spiritual experience or devotional practice [is] that it must lead directly to practical compassion. If your understanding of the divine [makes] you kinder, more empathetic and impelled you to express this sympathy in concrete acts of loving-kindness this [is] good theology. But if your notion of God [makes] you unkind, belligerent, cruel, or self-righteous, or if it [leads] you to kill in God’s name, it [is] bad theology.
Karen Armstrong, The Spiral Staircase
