Sometimes we Christians (myself included) want and really prefer the notion that I can:
1) Confess my sin, and
2) ....
that's it. I confessed it. That's all, right? Forgiven, forgotten. Let's move on.
Yet, as has already been mentioned, if the goal is full restoration and genuine spiritual care resulting in long term recovery, and help in abandoning sin and its harms and side effects--the work of the church's ministry in true shepherding is not comparable to the priest in the confessional dispensing penance like pharmacy prescriptions. Nor it is kindness to simply affirm the penitent sinner every week thereafter, showing him there is nothing to fear, no clouds about him so far as the church cares.
An analogy to a doctor's health-care provision is apt. If he's been called in to make a diagnosis and offer a cure, and he sees the patient bandaged and has swallowed a pain tablet, he may pat the fellow on the back and send him out a seeming success story. But suppose the doc knows the man should have more and ongoing care? Sure, the patient might get well without any follow up care, could have no setbacks, could avoid strains and new injury--though the doctor makes no sign that he would like to monitor the progress of healing, and even improvement.
But equally, or maybe even more likely, the patient will struggle even as he thinks he's got all under control. No one is monitoring him, but informally and from afar. His mom calls him a week later, a month later still, to see if he seems OK. How is he doing, in fact? Only he knows for sure, and he could be kidding himself or just ignorant.
As a doctor owes his patient a certain ongoing interest and sharing his expertise, even more does the church's ministry owe its members oversight especially when they have fallen and only recently arisen. The fact this ministry mentioned in the OP has asked for a "voluntary" cooperation from one of its injured members should be anything but a barrier to that cooperation.
Perhaps I am the kind of person who would tell an attentive physician "Buzz off, doc." And perhaps doctors and elders can be overbearing and pushy in offering their services. But what is the evidence for so concluding? Only that such care was being offered? It seems a bit of peremptory rejection of the attentions that from this perspective seem presented by serious and loving providers.
