"The Bible says of God only two things in terms of an 'is': That God is light and God is love. And wherever there's love, there's God in some fashion," said Eggebeen, himself a dog lover. "And when we love a dog and a dog loves us, that's a part of God and God is a part of that. So we honor that."

The weekly dog service at Covenant Presbyterian is part of a growing trend among churches nationwide to address the spirituality of pets and the deeply felt bonds that owners form with their animals.

Traditionally, conventional Christians believe that only humans have redeemable souls, said Laura Hobgood-Oster, a religion professor at Southwestern University in Georgetown, Texas. But a growing number of congregations from Massachusetts to Texas to California are challenging that assertion with regular pet blessings and, increasingly, pet-centric services, said Hobgood-Oster, who studies the role of animals in Christian tradition.

"It's the changing family structure, where pets are really central and religious communities are starting to recognize that people need various kinds of rituals that include their pets," she said. "More and more people in mainline Christianity are considering them to have some kind of soul."
