Wishing to establish the obligatory force of his example of abstinence, the Apostle points to his dignity as a herald of Christ. The Corinthians, converted by him to Christ, could not doubt this dignity.
They had not only heard his word and seen the great miracles performed by him. They also bore in themselves various gracious gifts, both common and extraordinary, which had appeared in them through the faith proclaimed by the Apostle.
If the Apostle was so powerful, then he was no less free than those who, reasoning in an allegedly free way, ate things sacrificed to idols.
Pointing to his apostolic dignity in another epistle to the Corinthians, the Apostle writes: “The signs of an Apostle were performed among you in all patience” (2 Cor 12:12).
Here too the Apostle passes to the same instructive thought concerning his ascetic patience. It was shown in his abstaining from the use of that to which he had a full right.
