“Second Corinthians is a fertile source for theological reflection. To be sure, Paul was not what we would today call a systematic theologian. His letters are not theological treatises. Paul was a founder of local churches who, in the course of exercising pastoral care over them, wrote letters that dealt with practical matters and pressing concerns. Nevertheless, he tended to think theologically. In the course of handling even the most mundane affairs that arose, his strategy was to bring the realities of faith to bear on them.”
