On the contrary, they valued more highly the preaching distinguished by eloquence (Acts 14:18). Perhaps the Apostle partly had this in mind when he called the Corinthians carnal.
In general, however, the Corinthians were carnal because of their sinfulness.
They were also carnal because not all of them at once received Christianity in the full breadth of its teaching and holiness of life.
But so that this might not seem a humiliation to the newly converted, the Apostle calls them babes in Christ.
He says that, in keeping with their new beginning in the Christian faith, he offered them teaching proportionate to their weak capacity.
In this he acted like a tenderly loving mother, or like a very experienced tutor.
The Corinthians' shortcomings were envy, disputes, and divisions. For their sake the Apostle called them carnal.
This is clear from the following reference to disputes about the superiority of teachers of the faith. These disputes arose from the Greeks' customary attitude toward teachers.
St. John Chrysostom here resolves the question: "How does the Apostle call the Corinthians carnal, when they had so many spiritual gifts and he himself praised them so much at the beginning?"
He answered: "In exactly the same way as those were carnal of whom the Lord said, 'Depart from Me, I do not know you, you workers of iniquity' (Mt 7:23).
Therefore even one who performed signs could be carnal. If grace always sought the worthy, there would be neither Baptism, nor the consecration of the Body of Christ, nor offerings.
God acts even through the unworthy, and the grace of Baptism suffers no harm from the life of the priest.
Man contributes nothing of himself in them, that is, in the mysteries. All this is the work of God's power. He acts upon us in the mysteries."
The Apostle unfolds further this view of Christ's ministers as instruments of divine providence.
