Co-founded in 1889 by Charles & Myrtle Fillmore in Kansas City, MO, Unity is rooted in this couple’s desire for physical healing. Both were well versed in world religions. Myrtle discoverd that by repeating the affirmative prayer, "I am a child of God, therefore, I do not inherit sickness," and praying for perfect health for two years, she was healed of terminal tuberculosis. Charles used the same type of prayer that affirmed God’s presence within him, and he was healed of injuries that had hampered him since childhood. Their friends soon began practicing affirmative prayer, the Fillmores began writing about their beliefs, and the Unity movement was born.

It was never intended to become a religion, but evolved into one as interest in these gentle metaphysical ideas grew. The Fillmores never insisted that those who sought their help forsake medical attention. Unity supports the medical community and still believes in people getting help in every way they can. Unity is built on the belief in the healing power of prayer.
