"For the preaching of the cross is to them that perish foolishess:but unto us which ARE saved, it is the power of God." (1 Cor. 1:18).
It may be, indeed it certainly is, that if we preach the Gospel we will meet with quite astonishing negative reactions. But that does not excuse being offensive either deliberately or carelessly. And to consider all negative responses as indications that one is speaking the truth is logically ridiculous and spiritually perilous.
Since a major issue in the Corinthian Church was division as people went off after different teachers, all or many of whom attracted adherents by claiming authority based on wisdom and/or charisms, one might reasonably view I Cor 13 as a reminder that if the claimed gifts or abilities result in division, one ought at least to check to see if the supreme charism and virtue might need a little more cultivation.
I was thinking the other day of two Christians.
-- One spent his life thinking great thoughts and making great arguments. But he never shared his thinking with anyone.
--The other spent his time proclaiming the Gospel, but with such venom and glee at the discomfiture of others that soon no one listened any more.
In my mind, the second is worse, because he drove people away from the saving truth, while at least the first one had no effect on others. But neither did a whole lot in the making disciples of all nations business.
