Tertullian — On Monogamy 10
From this point I see that we are challenged by an appeal to the apostle; for the more easy apprehension of whose meaning we must all the more earnestly inculcate (the assertion), that a woman is more bound when her husband is dead not to admit (to marriage) another husband. For let us reflect that divorce either is caused by discord, or else causes discord; whereas death is an event resulting from the law of God , not from an offense of man; and that it is a debt which all owe, even the unmarried.
Therefore, if a divorced woman , who has been separated (from her husband) in soul as well as body, through discord, anger , hatred , and the causes of these — injury, or contumely, or whatsoever cause of complaint — is bound to a personal enemy, not to say a husband, how much more will one who, neither by her own nor her husband's fault, but by an event resulting from the Lord's law, has been — not separated from, but left behind by — her consort, be his, even when dead, to whom, even when dead, she owes (the debt of) concord? From him from whom she has heard no (word of) divorce she does not turn away; with him she is, to whom she has written no (document of) divorce ; him whom she was unwilling to have lost, she retains.
She has within her the licence of the mind , which represents to a man , in imaginary enjoyment, all things which he has not. In short, I ask the woman herself, Tell me, sister, have you sent your husband before you (to his rest) in peace? What will she answer? (Will she say), In discord? In that case she is the more bound to him with whom she has a cause (to plead) at the bar of God . She who is bound (to another) has not departed (from him). But (will she say), In peace? In that case, she must necessarily persevere in that (peace) with him whom she will no longer have the power to divorce ; not that she would, even if she had been able to divorce him, have been marriageable.
Indeed, she prays for his soul , and requests refreshment for him meanwhile, and fellowship (with him) in the first resurrection; and she offers (her sacrifice ) on the anniversaries of his falling asleep. For, unless she does these deeds , she has in the true sense divorced him, so far as in her lies; and indeed the more iniquitously — inasmuch as (she did it) as far as was in her power — because she had no power (to do it); and with the more indignity, inasmuch as it is with more indignity if (her reason for doing it is) because he did not deserve it. Or else shall we, pray , cease to be after death, according to (the teaching of) some Epicurus , and not according to (that of) Christ?
