If this be not so, then the very next marriage which is given, where the man may not marry his father's second wife, or, as it is commonly called, his step-mother, in the case of the woman would be, "but the woman may marry her step-father." Such a thing is contrary to the law of God, and contrary, besides revolting, to nature and common sense or the right use of reason.
Then we say,—as surely cannot but be right, for God starts us with it in the first forbidden union,—that what applies to the man equally applies to the woman in a similar case.
So we go on down the list, putting the case of the woman in the way God commences.
* 2. A man may not marry his father's wife.
∴ A woman may not marry her mother's husband.
* 3. A man may not marry his step-sister.
∴ A woman may not marry her step-brother.
4. A man may not marry his granddaughter.
∴ A woman may not marry her grandson.
* 5. A man may not marry his half-sister.
∴ A woman may not marry her half-brother.
6. A man may not marry his aunt.
∴ A woman may not marry her uncle.
* 7. A man may not marry his aunt (by marriage).
∴ A woman may not marry her uncle (by marriage).
