1 Corinthians 1:17-31
For Christ sent me not to baptize, but to preach the gospel: not with wisdom of words…
The force of κενὸς (cf. 1 Corinthians 15:14; Romans 4:14) may be conveyed by the words "empty of content, unreal, not having objective existence, consisting only of opinions, sentiment speculation." The Cross of Christ is a real cause in the moral order of things. To substitute a system of notions, however true and ennobling, for the fact of Christ's death, is like confounding the theory of gravitation with gravitation itself.
