August 6, 1221: Dominic, founder of the Order of Preachers (or Dominicans), dies, having just confessed his darkest sin—that, though he had always been chaste, he enjoyed talking with younger women more than older ones.

At his death, he had thousands (see issue 73: Thomas Aquinas).
August 6, 1651: Francois Fenelon, Roman Catholic priest and mystical theologian, is born in Perigord, France. His 1697 Explication des Maximes des Saintes is still in print under the title Christian Perfection.
August 6, 1774: Ann Lee and a small band of her followers arrive in New York from Liverpool, England. Though known as the "Shaking Quakers" and later the "Shakers," the millenarian communal society preferred to call itself the United Society of Believers in Christ's Second Coming. They initially did not receive a warm welcome, as they were British and advocated pacifism and celibacy.
