17 At the request of the reverend presbyters, as I have said, I have devoted to the dictation of these remarks the labour of a single night, for my brother Sisinnius is hastening his departure for Egypt, where he has relief to give to the saints, and is impatient to be gone. If it were not so, however, the subject itself was so openly blasphemous as to call for the indignation of a writer rather than a multitude of proofs. But if Dormitantius wakes up that he may again abuse me, and if he thinks fit to disparage me with that same blasphemous mouth with which he pulls to pieces Apostles and martyrs, I will spend upon him something more than this short lucubration. I will keep vigil for a whole night in his behalf and in behalf of his companions, whether they be disciples or masters, who think no man to be worthy of Christ's ministry unless he is married and his wife is seen to be with child.
