If you take the old route of putting justification, in its traditional meaning at the centre of your theology, then you will always be in danger of sustaining some sort of individualism. This wasn’t so much of a problem in Augustine’s or even in Luther’s day when society was much more bound together than it is now. But… in contemporary post-modernism individualism has been all the rage…

Justification is itself the ecumenical doctrine, the doctrine that rebukes all our petty and often culture-bound church groupsings, and which declares that all who believe in Jesus belong together in the one family.

Justification declares that all who believe in Jesus Christ belong at the same table, no matter what their cultural or racial differences.

One is not justified by faith by believing in justification by faith. One is justified by faith by believing in Jesus.

– N.T. Wright, What Saint Paul Really Said
