I found the follow commentary in a parish bulletin which I think is put out by the Western American Diocese, here.
“…to spare you I came no more to Corinth…”
2 Cor. 1:21-2:4, Fourteenth Sunday after Pentecost
COMMENTARY ON 2 CORINTHIANS
The Apostle Paul writes to the Corinthians the true reason why he does no longer come among them: he is sparing them from a confrontation. It is through graciousness that he does not return to them. The pastor never rejoices when his flock errs and moves away from God. The purpose of Church discipline is never for the leader to exercise harsh authority or dominion, but rather to call for repentance, reconciliation with the Church, and a true renewal in the joy of the Spirit. Pastoral correction brings both agony to the overseer and abundant love for the one being corrected. Church discipline is never punishment. It will never be too severe. Rather, it is a spiritual medicine meant to reunite the sinful person to God.
