A thought on what Lonergan demonstrates. 
The article is about a theological work. However, his methodology, the basis of his process is based upon how "I" know, our insatiable urge to know and exploration of how we know.  The epitome of secularism?
No, the search, the quest, the questioning that leads or can lead to the image and likeness of God.  It does not replace revelation; it is the "image" seeking that which it is the image of.
The process applies analogically to "WE". Christians, led historically by Catholicism, has focused on the diminution of self, of person, "emptying oneself" as what is pleasing to God: "abnegation, mortification and self-denial", the will suffering of submission towards nothingness.   As  Christians believe we depend on "Other". It (should) takes little reflection to realize that we depend on "other", as well on innumerable levels. The question is do "seek the common good" as nurturers or do we exploit, use, manipulate?
Civility is human THEN Christian.
