Daniel C. Maguire discusses the pro-choice option in ten of the world's religions. He also offers this overview of the spiritual practice of gratitude.
"What strikes me in the Native religions is their elevation of gratitude to the top of the virtues. Their liturgies and rituals almost invariably begin with gratitude. They are thankful for the wind and the water, the plants and the trees, the fish and the animals, and for one another. Many Christian liturgies begin with repentance and confession of sin. The Natives start with exuberant thanks. Faith, hope, and charity top the Christian list of virtues. Gratitude is more basic, the Natives say. What do we have that we have not received? To be is to be a recipient. Ingratitude is almost a form of psychosis, a detachment from reality, and it is dangerous. If you don't appreciate what you've got on this generous host of an earth, or even in a personal relationship, you may lay it waste. As a species, we won't perish from a lack of information, said Abraham Heschel, but from a lack of appreciation. Gratitude is a cure for blindness."
