DETROIT — A March 24 day of spiritual reflection will offer families a lot to chew on in relation to Archbishop Allen H. Vigneron’s pastoral letter, Unleash the Gospel.

The twice-yearly free retreats at Sacred Heart Major Seminary grew out of the Changing Lives Together initiative and have blossomed to include elements of Archbishop Vigneron’s letter, said Tom Scholler, associate director of development and stewardship for the Archdiocese of Detroit.

This spring’s retreat, which starts at 9:30 a.m. and continues until 3:15 p.m., will focus on the role of families in the new evangelization.

“Because families are such an important part of the pastoral letter, the theme is ‘Building Families on the Foundation of Jesus,’” Scholler said. “Typically these days have three presentations and a Mass celebrated by one of the bishops, as well as an opportunity for reconciliation and intercessory prayer.”

Talks will be provided by Fr. Joseph Horn, director of priestly vocations, on discovering one’s vocation within the family; archdiocesan evangelization coordinator Michael King on awakening the “domestic church;” and Patricia Gonyeau, a catechist at St. Vincent Pallotti Parish in Wyandotte, on keeping faith through challenges in family life.

Auxiliary Bishop Robert Fisher will celebrate Mass at 12:15 p.m.
