Shadow and Act has an exclusive preview of this week’s Greenleaf episode.

In the below clip, Mae (Lynn Whitfield) preaches beautifully at “A Day with Lady Mae” as the Bishop (Keith David) fears he may lose Calvary. Grace (Merle Dandridge) gets a paternity test with Aaron (William H. Bryant Jr.) and works with Jacob (Lamman Rucker) to clear their family name.

The episode airs Wednesday, Nov. 14 on OWN.

Watch below:

Greenleaf recently got renewed for a fourth season at the network.

In season three of Greenleaf, all the turbulent forces that Grace’s (Merle Dandridge) return to Memphis unleashed threaten to destroy not just the church her family built, but the family itself. Fallout from last season’s shocking revelation of Bishop’s (Keith David) infidelities with Lady Mae’s (Lynn Whitfield) sister, as well as reverberations from his current dalliance with that insidious Jezebel, Rochelle Cross (LeToya Luckett) lead to all-out war in the Greenleaf home, setting the Bishop and Lady Mae on a collision course that, unless God or Grace intervenes, can only end one way: divorce.

The series also stars Desiree Ross, Lamman Rucker, Deborah Joy Winans, Rick Fox, Tye White, Kim Hawthorne and Lovie Simone.
