Who's to blame?

Ryan T. Anderson argues heterosexuals are:

"It was heterosexuals in the ’60s and ’70s who began to live as if marriage should last only as long as the romantic feelings last, replacing “as long as we both shall live” with “as long as we both shall love.” If what makes a marriage is merely consenting adult romance, then there is no reason why marriage has to be permanent or limited to two persons, much less sexually exclusive."

"As a result, cohabitation, no-fault divorce, extramarital sex, non-marital childbearing, pornography, and the hook-up culture became normalized, and each contributed to the breakdown of the marriage culture...The redefinition [of marriage is], rather, the logical conclusion of these problems. The problem is that these conclusions follow a train of logic that begins from utterly false premises."

Unfortunately, within the context of marriage Christians have not been innocent of these sins. Moreso, sometimes we may find ourselves unrepentant of these sins. As Christians, we know that Scripture teaches that marriage should be a reflection of the selfless, transcendent love has been showed toward us.

"Husbands, love your wives, as Christ loved the church and gave himself up for her, that he might sanctify her, having cleansed her by the washing of water with the word, so that he might present the church to himself in splendor, without spot or wrinkle or any such thing, that she might be holy and without blemish. In the same way husbands should love their wives as their own bodies. He who loves his wife loves himself."
- Ephesians 5:25-28

Although we will continually face temptation, we ought not to acquiesce in the struggle against our sinful desires. We fight temptation just as St. Paul did, all the while resting the comfort of Christ's unending mercy.

"For I delight in the law of God, in my inner being, but I see in my members another law waging war against the law of my mind and making me captive to the law of sin that dwells in my members. Wretched man that I am! Who will deliver me from this body of death? Thanks be to God through Jesus Christ our Lord! So then, I myself serve the law of God with my mind, but with my flesh I serve the law of sin."
- Romans 7:22-25
