“When Titus returned, he carried us away with delight, when he told us so many pleasing things about you. Titus was comforted concerning you. By what was he comforted? By your virtue, by your correction.
“Therefore he adds: ‘reporting to us your longing, your mourning, your zeal for me.’ This is what comforted Titus. Do you see? He presents him too as greatly disposed toward the Corinthians.
“He regarded their good reputation as a consolation for himself. When he came, he boasted of it before Paul as his own good. And see with what warmth the Apostle expresses this: ‘your longing, your mourning, your zeal.’
“For they were indeed bound to weep and grieve that blessed Paul had been so angered with them and had been absent from them so long. He overflows with joy because he deeply moved them.”
It seems to me that this was said not only as consolation for what had gone before, but also to stir up still more those who had fulfilled what was required.
For I think that some were subject to the former reproofs and did not deserve such praise. Yet he does not separate them. On the contrary, he praises and reproves all together, leaving each one to choose what belongs to him.
In this way the reproaches became bearable, and the praises stirred them to greater zeal.
