12.
If you had not now a wife, I would say to you what we said at Tubunae, that you should live in the holy state of continence, and would add that you should now do what we prevented you from doing at that time, namely, withdraw yourself so far as might be possible without prejudice to the public welfare from the labours of military service, and take to yourself the leisure which you then desired for that life in the society of the saints in which the soldiers of Christ fight in silence, not to kill men, but to "wrestle against principalities and powers, and spiritual wickedness," 1 that is, the devil and his angels. For the saints gain their victories over enemies whom they cannot see, and yet they gain the victory over these unseen enemies by gaining the victory over things which are the objects of sense. I am, however, prevented from exhorting you to that mode of life by your having a wife, since without her consent it is not lawful for you to live under a vow of continence; because, although you did wrong in marrying again after the declaration which you made at Tubunae, she, being not aware of this became your wife innocently and without restrictions. Would that you could persuade her to agree to a vow of continence, that you might without hindrance render to God what you know to be due to Him! If, however, you cannot make this agreement with her, guard carefully by all means conjugal chastity, and pray to God, who will deliver you out of difficulties, that you may at some future time be able to do what is meanwhile impossible. This, however, does not affect your obligation to love God and not to love the world, to hold the faith stedfastly even in the cares of war, if you must still be engaged in them, and to seek peace; to make the good things of this world serviceable in good works, and not to do what is evil in labouring to obtain these earthly good things,--in all these duties your wife is not, or, if she is, ought not to be, a hindrance to you.
These things I have written, my dearly beloved son, at the bidding of the love with which I love you with regard not to this world, but to God; and because, mindful of the words of Scripture, "Reprove a wise man, and he will love thee; reprove a fool, and he will hate thee more," 2 I was bound to think of you as certainly not a fool but a wise man.
