_Answ._ I think not; 1. Because not forbidden by God. 2. Because none of that same rank are forbidden; that is, none that on both sides are two degrees from the root. I refer the reader for my reasons to a Latin Treatise of Charles Butler on this subject, for in those I rest. As all the children of Noah's sons did marry their cousin-germans, (for they could not marry in any remoter degree,) so have others since without reproof, and none are forbidden. 3. But it is safest to do otherwise, because there is choice enough beside, and because many divines being of the contrary opinion, may make it matter of scruple and trouble afterwards, to those that venture upon it without need. _Quest._ IV. What would you have those do that have married cousin-germans, and now doubt whether it be lawful so to do? _Answ._ I would have them cast away such doubts, or at least conclude that it is now their duty to live peaceably in the state in which they are; and a great sin for them to be separated on such scruples. The reason is, because, if it be not certain that the degree is lawful, at least no man can be sure that it is unlawful. And for husband and wife to break their covenants and part, without a necessary cause, is a great sin; and that which no man can prove to be a sin, is no necessary or lawful cause of a divorce. Marriage duties are certainly commanded to the married, but the marriage of cousin-germans is not certainly forbidden. Therefore if it were a sin to marry so, to them that doubted; or if they are since fallen into doubt whether it was not a sin; yet may they be sure that the continuance of it is a duty, and that all they have to do is to repent of doing a doubtful thing, but not to part, nor to forbear their covenanted duties. No, nor to indulge or suffer those troublesome scruples, which would hinder the cheerful discharge of their duties, and the comfortable serving of God in their relations. _Quest._ V. What should those do that are married in those degrees which are not forbidden by name in Lev. xviii. and yet are at the same distance from the root with those that are named, and seem to have the same reason of unlawfulness?
