This work examines Mary, particularly as she stood at the foot of the cross, as a model for participating in a Trinitarian life of communion. O’Byrne outlines two theological themes at the core of Lubich’s thought — “unity” and “Jesus forsaken.” Upon this background she analyzes Lubich’s Mariology, from the moment of Mary’s first yes at the Annunciation to her second at the foot of the cross. O’Byrne then turns her attention to Lubich’s profound understanding of Mary in her desolation as an anthropological model.
