Augustine of Hippo

The apostle says in a certain place, "If I yet pleased men, I should not be the servant of Christ;" and the same apostle says in another place, "I please all men in all things," and adds the reason, "Not seeking mine own profit, but the profit of many, that they may be saved."... What the apostle says, then, in the first of these passages, "If I yet pleased men, I should not be the servant of Christ," is to be understood as if he said, If the good things which I do were done by me with human praise as my motive, if I were puffed up with the love of praise, I should not be the servant of Christ. The apostle, then, wished to please all men, and rejoiced in pleasing them, not that he might himself be inflated with their praises, but that he being praised might build them up in Christ.
