Presidential candidate Marianne Williamson will deliver the sermon on Sept. 1 at Hillside International Truth Center in Atlanta.

Williamson, an author and lecturer, is among a crowded field of  Democratic candidates vying for the  nation’s top job. She will speak during the 10 a.m. service at the church, 2450 Cascade Rd. S.W.

A book signing will follow the services. Hillside was founded 48 years ago by Bishop Barbara L. King.

Williamson, considered a long shot to get to the White House, has written more than a dozen books, including several New York Times number one bestsellers.
