The bottom line, though, is that this tends to sidestep a crucial fact: the Church needs to be forgiven. She's a mess. She's been a mess. She's hurt people time and again, been beset by sin that would take years simply to recount. And yet, her Groom has been made her clean, is making her clean, and will make her clean. That's the reality, and it's hard to reconcile our own hearts to it. It is neither accurate or edifying to disconnect ourselves with the Church's history and pretend we're starting from scratch with "Jesus and me/us." Trying to create a church that doesn't need forgiveness because it's suddenly, after thousands of years, "being done right," is at once denial of reality and idolatry.
Is the gospel powerful enough for the Church to be forgiven? If it is, then that's what we can invite believer and non-believer alike to do instead of playing language games. That's where Miller jumped right back on track—his chapter on confession (where this is drawn from) concludes with some powerful stories of requested and granted forgiveness.
Let me close with a disclaimer that should already be implied: these thoughts are all based on my own perspective and preferences. The Body, the Church is much bigger than me, by design. I'm not very fluffy, and maybe the things I see as fluffy are genuinely helpful to bringing some nearer to Him. I simply don't think rejargoning the Church is a good way to go, and it runs the risks of sidestepping important parts of who we are.
