Father Ron's Daily Reflection

Sunday, Dec 2, 2017 - +May the Grace of this Advent Season, through the intercession of Mary and Joseph,  lead us to a faith that is not about certainty, but a faith that helps us live the uncertainties of daily life as we remain Watchful and Alert to the Second Coming of Jesus+

December 4, 2017 - +May the veneration of the saints through their trust, love, zeal, patience, and perseverance , fostered by Saint John Damascene, lead us to a centurion-like unconditional faith as instruments of compassion and advocates of reconciliation in this life as we seek the Eternal Peace of the Heavenly Kingdom+
