The married should be advised that they endure with mutual patience those things that occasionally bring displeasure and that they exhort one another to salvation … They should be advised that they not worry themselves so much about what they must endure from their spouse, but consider what their spouse must endure on account of them. For if one really considers what must be endured on his account, it is all the easier to bear the things of others
–Saint Gregory the Great (c. 540-604)
