12. For I neither received it from man. What then? shall the authority of the word be diminished, because one who has been instructed by the instrumentality of men shall afterwards become a teacher? We must take into account, all along, the weapons with which the false apostles attacked him, alleging that his gospel was defective and spurious; that he had obtained it from an inferior and incompetent teacher; and that his imperfect education led him to make unguarded statements. They boasted, on the other hand, that they had been instructed by the highest apostles, with whose views they were most intimately acquainted. It was therefore necessary that Paul should state his doctrine in opposition to the whole world, and should rest it on this ground, that he had acquired it not in the school of any man, but by revelation from God. In no other way could he have set aside the reproaches of the false apostles.
The objection, that Ananias (Acts 9:10) was his teacher, may be easily answered. His divine instruction, communicated to him by immediate inspiration, did not render it improper that a man should be employed in teaching him, were it only to give weight to his public ministry. In like manner, we have already shown, that he had a direct call from God by revelation, and that he was ordained by the votes and the solemn approbation of men. These statements are not inconsistent with each other.
