From: God the Teacher of Mankind, section on Matrimony, by Fr. Michael Müller:
“Those, then,” says St. John Chrysostom, who have set their hearts on marriage, ought not to venture on a matter so grave without mature deliberation. If you buy a house, you carefully examine its condition, and whether it will suit you. Before you engage your servants, you use every means to know about their health, their good sense, their mental qualities and moral dispositions. If the house proves defective, you can sell it again. If your servants are useless or unmanageable, you can free yourself of them. But you cannot dispose of your wife [husband]. She is joined to you for life, and is always with you in the house.
