From Invertebrate Spain by José Ortega y Gasset:

Strict Catholic dogma limits itself to demanding that the faithful admit the canonical definition of God, and leaves each one’s fancy free to imagine Him and to feel Him in its own peculiar way. Taine speaks of a child who was told that God was in the sky. “In the sky, like the birds?” she exclaimed. “Then he must have a beak.” That child could be a Catholic; there is nothing in the catechism’s definition which prevents God from having a beak.
