On Sundays and major feast there are always three readings. The First Reading is usually taken from the Old Testament. Texts were chosen to prepare for the gospel, following such principles as prophecy-fulfillment or continuity of themes. In keeping with ancient tradition the First Reading during the Easter Season is taken from the Acts of the Apostles, which show how the early Church gave witness to the paschal mystery.
On weekdays there are only two readings. During Advent and Lent the first is always from the Old Testament and is related to the Godpel. Within Ordinary Time selections from the Old and New Testaments apprear, but no attempt was made to harmonize the readig with the Gospel.
As St. Augustine so succinctly state it, “In the Old Testament the New is hidden, in the New Testament, the Old appears.” (Quaest. in Hept. 2, 73)
Questions for Reflection:
1. What are the advantages/disadvantages of having three readings on Sundays and Feast Days?
Scripture: Blessed are those who hear the word of God and obey it (Luke 11:28)
