In the first reading Paul, most properly introduced himself to a Rome he had never visited.
He called himself a slave, appointed by that Christ to whom all the prophets had looked forward: that Christ, descended from David, who had been established as Son of God in power by his unique triumph over death.
If I might stress a point beyond what seems possible, I would like to compare the formality of Paul's introduction to the filthy informality of men eating in the costly restaurants where once coats and ties were obligatory.
Now, men come dressed in dirty gray "T" shirts, cut away here and there to show off tattoos. They lump over shorts that are too small for them. They seem to be denying the dignity of men made in God's image.
