7. Could Paul teach in opposition to his own act? He had at Corinth forgiven sin through penance, how could he himself speak against his own decision? Since, then, he could not destroy what he had built, we must assume that what he says was different from, but not contrary to, what had gone before. For what is contrary is opposed to itself, what is different has ordinarily another meaning. Things which are contrary are not such that one can support the other. Inasmuch, then, as the Apostle spoke of remitting penance, he could not be silent as to those who thought that baptism was to be repeated. And it was right first of all to remove our anxiety, and to let us know that even after baptism, if any sinned their sins could be forgiven them, lest a false belief in a reiterated baptism should lead astray those who were destitute of all hope of forgiveness. And secondly, it was right to set forth in a well-reasoned argument that baptism is not to be repeated.
