Greet you warmly in the Lord.
I, Paul, write this greeting in my own hand.
The grace of the Lord Jesus be with you.
My love to all of you in Christ Jesus Amen.
The letter closes with a final appeal, and greetings from the Asian churches, especially fro Aquila and Priscilla, the leather workers in whose house Paul lived during his stay in Corinth.
Why?
The warm and loving final greeting he writes himself(the rest having been dictated to a secretary" a common practice)
