April 25th sees the coincidence of three observances this year: the Friday within the Octave of Easter, the feast of St Mark the Evangelist, and the Major Litanies, or Rogation Days. Traditionally, St Mark would be transferred to the next free day after Low Sunday, but the Major Litanies would be celebrated together with the Easter Octave, with a procession and a Mass. In the Breviary, the Litany of the Saints would be recited after Lauds by those who do not participate in a Rogation process. Our friend Fr Christopher Smith, a priest of the Diocese of Charleston, South Carolina and one of the writers at Chant Café, put together an excellent illustrated guide explaining both the Rogations and Ember Days, with a number of very useful quotes from various liturgical sources.
