John Chrysostom, on Heb 12:14

“Follow peace with all men, and holiness: without which no man shall see God.”

“"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. "Without which" (he says) "no man shall see the Lord." Which he also says in the Epistle to the Corinthians. "Be not deceived: neither fornicators, nor adulterers, nor idolaters, nor effeminate, nor abusers of themselves with mankind, nor covetous persons, nor thieves, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God." (1 Cor. vi. 9, 10.) For how shall he who has become the body of a harlot, how shall he be able to be the body of Christ?”
