I disagree that pelagianism and especially semi-pelagianism are no longer problems.
For many people, frankly, the catholic and orthodox approaches are inadequate, even harmful, because they fail to appreciate how much existential threats can drive people to despair. Many, many people never darken a church door because they are already condemned in their minds. That's why I think the Reformation is not finished, and really never will be until the appearance of our Lord again. The religion of natural man, the opinio legis, is alive and well. It exists all around us, not just in churches but in society at large. That is why even Christians need to hear the Gospel as Good News.
Rod Rosenblatt, a conservative Lutheran, has actually written a great deal about this phenomenon. People like this, people crushed by the Church or by perceived inadequacies, tend to shy away from religion altogether.
