I own Logos Bible Software 5.1b SR-3 (5.1.2.009), product name: Verbum. I am trying to use the Catholic Lectionary in my Diaconate Formation Class, but the readings in the Lectionary do not match the Mass readings. The Lectionary and the Mass readings for each day are very close, but not an exact match and some of the words such as the First Readings this week all begin with "Brothers & Sisters". This is not in the Verbum Lectionary. Can someone help me to understand why the Verbum Lectionary does not match the daily Mass readings? Or, what I need to do to get the readings to match?
