THE SIXTH COMMANDMENT.
The sixth behest is this: ‘Thou shalt do no whoredom;’ that is to say, thou shalt not desire carnal fellowship with other men’s wives.
In this behest is forbidden us all sin of the flesh, that one calls generally lechery. That is one of the seven deadly sins, though there are some branches that are not deadly sin, as are many motions of the flesh, all of which one cannot flee. And those one shall bring to naught and withdraw from as much as one can, not nourish nor pursue them, either by too much meat or drink, or by evil thoughts too long holden, or by evil handlings. For in such things one may have harm of soul. In this behest is forbidden all sins against nature, in whatever manner they are done, either in his own body or in others.
