Paul naturally begins his letters by introducing himself and perhaps his companion and then mentions the name of those to whom he writes, wishing them grace and peace. All the introductions to Paul's letters contain material for theological reflection, spiritual formation and prayer.

Today we read the much longer opening passage of the Letter to the Romans, which is more solemn and more theological than many of the others

Let us reflect especially on the titles which Paul uses in speaking of Jesus. He is Christ Jesus, Son of God, descendant of David, Jesus Christ our Lord, Jesus Christ, the Lord Jesus Christ. The difference between some of these titles may seem to be of very little importance, but all of them taken together sum up the mystery of the Incarnation, which is the meaning of Christmas.

The name "Jesus", stresses his humanity. The title "Son of God" stresses his divinity. When we speak of the "spirit of holiness that was in him" we remember that he was a man filled with the Holy Spirit and the second person of the Blessed Trinity. "Descendant" of David affirms that he is the promised Messiah.
