Chaput's book reminds me of this phrase from Francis:

*self-absorbed Promethean neo-pelagianism*

This appears to capture the criticism of many commenters and MSW.  Or, in other words, Chaput is convinced that his way is the only way to salvation - perfect Pelagianism.

To quote - "..dour Christians who confuse “solidity and firmness with rigidity; - today’s Pelagians are convinced that ‘salvation is the way I do things.’” 

"....(Chaput)ideology is the “Pelagian solution. This basically appears as a form of restorationism. In dealing with the Church’s problems, a purely disciplinary solution is sought, through the restoration of outdated manners and forms which, even on the cultural level, are no longer meaningful.”

“Instead of evangelizing, one analyzes and classifies others, and instead of opening the door to grace, one exhausts his energies in inspecting and verifying - In neither case is one really concerned about Jesus Christ or others.”
