Here in the Archdiocese of Cincinnati today (Nov. 3) is the Solemnity of the Dedication of Saint Peter in Chains Cathedral, so St. Martin de Porres gets bumped off the calendar.

Fr. Jason Williams, the young parochial vicar at St. Cecilia, has been catechetically promoting it this week as the capstone to a “Triduum” that began Tuesday with All Saints Day and continued Wednesday with the Solemnity of All Souls:

“The past three days give us a great opportunity to celebrate the Communion of Saints.  On Tuesday, All Saints Day, we honored the ‘Church Triumphant,’ the saints in heaven;  yesterday, All Souls Day, we prayed for the ‘Church Suffering,’ the souls in purgatory; and today, the Dedication of Saint Peter in Chains Cathedral, we recognize the ‘Church Militant,’ those of us here on earth and here in Cincinnati who stay true to the Faith and bring Christ to the world.”
