In communion with the holy Mother of God
Mary gave her consent in faith at the Annunciation and maintained it without hesitation at the foot of the Cross. Ever since, her motherhood has extended to the brothers and sisters of her Son "who still journey on earth surrounded by dangers and difficulties." Jesus, the only mediator, is the way of our prayer; Mary, his mother and ours, is wholly transparent to him: she "shows the way" (hodigitria), and is herself "the Sign" of the way, according to the traditional iconography of East and West.
