With the precision of a scholar, the empathy of a pastoral counselor, and the imagination of a poet, the author brings Martin Luther and John Wesley into a rich conversation about faith, spiritual formation, and ecclesial leadership. The result is a timely and compelling vision of theological and spiritual formation and leadership needed by a fractured church in a dangerous world. It belongs on the required reading list for students preparing for ministry in today's church.

McDonald skillfully and thoughtfully cultivates the “vineyards” of the spiritual lives and theologies of the reformer Martin Luther and evangelist John Wesley in order to bear good fruit for ecumenical dialogue. With practical guidance, McDonald invites contemporary Lutherans and Methodists to reflect on what they can learn from one another to stimulate deepening in their own tradition for the sake of growth in grace for the whole Christian communion.
