The First Reading
The first reading at Sunday Mass is usually from the Old Testament, except during the Easter Season when it comes from the Acts of the Apostles. On Sundays, the reading has been chosen by the Church to match up in some way with the Gospel. For example, the first reading on one Sunday is from the Book of Deuteronomy and has Moses speaking about the book of the law. The Gospel is Jesus speaking about what is written in the law.
During Weekday Masses, the first reading can come from either the New Testament, except from the Gospels, so Acts, the Epistles, or Revelation, or from the Old Testament. During the weekdays, the readings do not match up with the Gospel. One biblical book is read through, then another.
There was a writer named Marcion, in the early years of the Church (c.144), who wanted to reject the Old Testament. Marcion believed that the wrathful Hebrew God of the Old Testament was a separate and lower entity than the all-forgiving God of the New Testament. The Church rejected this as heresy.
As Christians, we value the Old Testament. It is God speaking to us, though the view of Christians is that of the writer of the Letter to the Hebrews:
In times past, God spoke in partial and various ways to our ancestors through the prophets (1:1)
God spoke in partial, fragmentary ways, but as Hebrews continues:
in these last days, He spoke to us through a Son (1:2)
As Christians, we see that the fullness of God’s speaking to us is He is the Word incarnate, the fullness of the Revelation of God.
The Old Testament predicts the coming of Jesus. It prepares us for the coming of Jesus. It lays ground work for the coming of Jesus. A Christian can’t help but read the psalms and the prophets and the rest of the Old Testament in the light of Jesus, the One who has come into the world. For the Christian, Jesus is the fulfillment of the work of God in the Old Testament.
To listen to only the New Testament without knowing the Old Testament would be like reading or watching the Return of the King without knowing The Fellowship of the Ring and The Two Towers; it could be a good thing, but there is much that would leave one going, “What’s happening?” “Who are these people?” “Why does that matter?” Reading the Old Testament helps give a more complete picture and helps give a full understanding of the story so far.
