It’s Valentine’s Day, the time when many American couples turn to romantic thoughts and gestures. (Think chocolates and roses.) What better occasion to think about the nature of Latter-day Saint marriages?

Bethany Brady Spalding and McArthur Krishna, authors of the bestselling “Girls Who Choose God” and “Guides to Heavenly Mother” series, have spent years exploring the influence of the divine feminine in the beliefs and practices of The Church of Jesus Christ of Latter-day Saints. Now they have turned their attention to a divine couple: Heavenly Parents.

They are deeply committed to the idea that marital equality is not just a human construct but also an eternal truth. In their new online workbook, titled “In the Image of Our Heavenly Parents: A Couple’s Guide to Creating a More Divine Marriage” from D Street Press, Spalding and Krishna, as well as Latter-day Saint therapists, explore these religious role models and 12 principles for improving marriages.

On this week’s show, the two editors, along with Jennifer Finlayson-Fife, a Latter-day Saint therapist in Chicago, discuss the new book and how earthly couples can build heavenly marriages.
