Lutheran pastors are not the Morality Police. They are God's Absolution Men. That is, I don't care what sins you commit as much as I care what sins are forgiven.
When I call people to repentance, it's always with this goal: that they would receive forgiveness. When I withhold forgiveness, it's always with this goal: that they would receive forgiveness. When I withhold the Lord's Supper from those who are impenitent, it's always with this goal: that they would receive forgiveness.
Proclaiming the Law to impenitent sinners, those who do not have Godly sorrow--repentance--over their sins and a desire to be free from them, is easily my least favorite thing to do as a pastor. But because I've been called to deliver God's Word and do God's work, I have no choice but to deliver the Law as well as the Gospel. And the Law is never the end of the story. The goal is that the sinner would allow God's Law to work, leading to repentance, so that I might get to do what is easily the most joyful thing I do as a pastor: deliver God's forgiveness.
Sometimes people complain that I'm singling out their particular sins. I don't think that's the case. I try to deal with all sin equally. Some types of sins seem more easily to become public. For the sake both of the one ensnared in such public sin and for the sake of the congregation who sees such sin, these public sins need to be dealt with with a call to repentance. And sin is never the problem. Impenitence is. There are only two categories of people: repentant sinners and unrepentant sinners. The first trusts in Jesus for forgiveness; the latter trusts in himself.
So I am not the Morality Police. I don't care about your sins. I'm the Absolution Guy. I care about God's forgiveness. And I want to do everything possible to see that you receive that forgiveness.
