The quest for Christian unity has traditionally been initiated at the international level between official leaders of Christian denominations, with the effects of their dialogue expected to trickle down to local Christian communities.

She draws directly from her experience equipping everyday Christians to know their own Christian tradition more thoroughly and to engage thoughtfully with separated Christians down the street and around the corner.
