[3.] “Follow peace with all men, and holiness.” What does he mean by “holiness” ? Chaste, and orderly living in marriage. If any person is unmarried (he says) let him remain pure, let him marry: or if he be married, let him not commit fornication, but let him live with his own wife: for this also is “holiness.” How? Marriage is not “holiness,” but marriage preserves the holiness which [proceeds] from Faith, not permitting union with a harlot. For “marriage is honorable” ( c. xiii. 4 ), not holy. Marriage is pure: it does not however also give holiness, except by forbidding the defilement of that [holiness] which has been given by our Faith.
