Saturday evening, I read about Catholic mass and communion. Sunday morning, I participated in sacrament at The Church of Jesus Christ of Latter-day Saints. Monday afternoon on Christmas eve, I'm reading the fifth chapter of the first epistle of John. In context of the holiday season, these experiences and words have drawn my attention to the birth of Jesus and the rebirth of Christ in each of us. They have drawn my attention to the core message of Christianity and Mormonism, which is human transformation into God -- theosis.
