There are many important details in Saint Paul's letters to which we pay little attention, for we concentrate on the main body of his doctrine.

Paul wrote his letters to instruct the new communities and to correct faults, often serious moral or doctrinal faults, which had arisen. But apart from the Letter to the Galatians, he does not begin with his instruction or with the problems.

After his introduction, where he wishes the community "grace and peace", he gives thanks to God for the goodness and fervour of these new Christians. This is true even in the case of the Corinthians, a particularly troublesome community. Because of his faith and trust in God, Paul was able to point to good things: "In Christ Jesus, they have been richly endowed with every gift of speech and knowledge." Paul's own preaching to them, his "witness", has been confirmed among them.

This expression of thanksgiving situates his letter in the presence of God in order to help the community understand that everything he says comes from faith and leads to greater faith, hope and love.
