["The cure" refers to the bronze serpent which healed the Israelites in the wilderness; the pope is comparing marriage to that journey.] The cure which God offers the people applies also, in a particular way, to spouses who “have become impatient on the way” and who succumb to the dangerous temptation of discouragement, infidelity, weakness, abandonment… To them too, God the Father gives his Son Jesus, not to condemn them, but to save them: if they entrust themselves to him, he will bring them healing by the merciful love which pours forth from the Cross, with the strength of his grace that renews and sets married couples and families once again on the right path.

The love of Christ, which has blessed and sanctified the union of husband and wife, is able to sustain their love and to renew it when, humanly speaking, it becomes lost, wounded or worn out. The love of Christ can restore to spouses the joy of journeying together. This is what marriage is all about: man and woman walking together, wherein the husband helps his wife to become ever more a woman, and wherein the woman has the task of helping her husband to become ever more a man. This is the task that you both share.

--Pope Francis, homily at Mass, September 14, 2014
