Icons are not necessarily images painted on wood, sometimes they correspond to a strong mental picture or interior representation. One way or the other, icons are like portable altars. They can be erected almost anytime and anywhere. Pilgrims -- such is our condition -- must travel lightly; icons do not weigh down the pilgrim's baggage. Icons are also like "moveable feasts." There is joy in worshipping God with icons, a joy to be shared and passed around.
There exists one such icon of the crucifixion scene. It has a strong built-in theology, reflecting all the important aspects of the Calvary event per John 19:25-27. This icon is the spiritual property of the Family of Mary, a family of Marianist religious and lay people, men and women. This treasure was handed down to them as a precious piece of family heirloom; it represents one of those foundational memories people cast in living hearts and minds. Such a memory helps create a collective identity: as people go along they enrich it and pass it on. This icon, this foundational memory or collective identity, is in fact a prayer called the Three O'Clock Prayer. Simple and unassuming as it may be, it captures not only the deepest memories of Christian faith, but it also conveys the particular spirit which continues to inspire the members of the Family of Mary.
