The Saints fall into distinct classes, common of apostles, supreme pontiff, confessors, martyrs etc. The Proper of the saints will tell you, right underneath the saints name, the Common and the page to turn to .(5). THE PROPER OF THE SEASON. right now we are in the seventh week after Pentecost. the Proper of the season is mostly used for Matins, Lauds, and Vespers , Depending the the Office being said or the class of the office.
