Why are there 2 readings at mass?

In Catholic Mass, there are typically two readings from the Scriptures to provide a richer understanding of the faith. The first reading usually comes from the Old Testament, highlighting the history and prophecies that foreshadow Christ, while the second reading is from the New Testament, often focusing on the teachings of Jesus or the apostles. This structure allows for a balanced reflection on salvation history and the message of the Gospel, encouraging deeper spiritual growth and connection to both Testaments.
