Feast of the Ascension Martyrs of Persia (17th–18th centuries). Ascension has an Afterfeast of eight days. The Sunday after Ascension is the Sunday of the Holy Fathers of the First Ecumenical Council at Nicaea. This council formulated the Nicene Creed up to the words, "He (Jesus) ascended into heaven, and sits at the right hand of the Father; and shall come again, with glory, to judge the living and the dead; Whose kingdom shall have no end." The Afterfeast ends on the following Friday, the Friday before Pentecost. The next day is appropriately a Saturday of the Dead (general commemoration of all faithful departed).
