O ALMIGHTY God, who by your blessed Son did call Matthew from the receipt of custom to be an Apostle and Evangelist: Grant us grace to forsake all covetous desires, and inordinate love of riches, and to follow the same thy Son Jesus Christ, who lives and reigns with you and the Holy Spirit, one God, world without end.
Isaiah 33:13-17; Psalm 119:65-72; 2 Corinthians 4:1-6; Matthew 9:9-13
Before Saint Matthew was an Evangelist (Gospel-writer) and Apostle, he was a tax collector – a profession known for its extortion and love of money. Thus the Collect, Old Testament reading, and Psalm all have references to the superiority of following Christ over having lots of money. Going deeper, there is especially the superiority of following God’s Law and Gospel. As the Epistle describes, the world is blinded to the Gospel unless God opens their eyes with the light of Christ. This is what Jesus did for Matthew, and what Matthew subsequently sought to do for others, along with the other Apostles.
