108

What doth the seventh command teach us?

That all uncleaness is accursed of God, and that therefore we must, with all our hearts, detest the same (Eph. 5;3), and live chastely and temperately, whether in holy wedlock, or in single life (Heb. 13;4).

109

Doth God forbid, in this command, only adultery and such like gross sins?

Since both our body and soul are temples of the Holy Ghost, he commands us to preserve them pure and holy (1 Cor. 3;16); therefore he forbids all unchaste actions, gestures, words, thoughts, desires, and whatever can entice man thereto (Matt. 5;28).
