The article reminds up of Jesus' words , "Physician heal thyself", and the need for personal virtue. Who would argue against this? 

But the quote  and the Catholic point about virtue reminds us that personal reform and  goodness come first; not only in terms of personal salvation but also with respects to  society. A good society depends upon good people. 

The above underscores a great divide which separates many in the Church. Liberals seem to place social relationships and structures above matters of personal virtue and belief. They stress the "systemic" nature of sin, and downplay personal responsibility. They see social activism and fixing the "system" as the way to "salvation". In this scenario they attribute almost church like attributes to the state and confer upon it amoral superiority. 

Sin is thought of in terms of Social attitudes regarding certain social categories (women, aliens, blacks, gays etc...), and true sin is  downplayed.
