An excellent point—the church isn't helping people even though we have the ability to do so. We do it with other addictions, so why not pornography?
I think the answer lies in defining what healthy sexuality is in the light of Christ. And that requires a whole lot of honesty about bodies in relationship, the beauty of the nude (not just models!), God's creation of the inherent goodness of sex and how, along with every other good, we distort it.
Hiding from sexuality has enabled all kinds of behaviors in churches that go totally against the gospel, and not just pedophilia. When these are exposed, the hypocrisy of Christians as a whole and pastors in particular is devastating. Just ask ex-archbishop Justin Welby, among many other leaders who have lost their ministries to the exposure of covert sin.
Perhaps we can start here:
"Therefore whatever you have said in the dark will be heard in the light, and what you have whispered behind closed doors will be proclaimed from the housetops." Luke 12:3
and
"What I say to you in the dark, tell in the light, and what you hear whispered, proclaim from the housetops." Matt. 10:27
