In the greeting of 1 Corinthians, Paul introduces 3 themes of the letter:  1) Paul is an authoritative emissary for Jesus Christ; 2) God chose Paul for this role;  and 3) speech and knowledge are gifts from God that we ought to view wisely.  We'll also contrast 2 ways to approach studying this letter.  One perspective finds little value in some of the practical problems.  The other perspective leads to wisdom that can be applied to any situation.
