The Mass · Lesson 4 of 10

Why These Readings? The Liturgy of the Word

At Mass God speaks to us through readings arranged in a cycle, so that over three years of Sundays we hear much of the Bible, with the Old Testament reading pointing to the Gospel.

This is a summary of Lesson 4 of The Mass, Explained. The full lesson takes about 3 minutes in the Saints Light app.

What this lesson teaches

  • Sundays have a first reading, a psalm, a second reading and the Gospel, followed by the homily.
  • Sunday readings follow a three-year cycle: Year A Matthew, Year B Mark, Year C Luke, with John woven through.
  • The first reading usually matches the Gospel, showing how the Old Testament points to Christ.
