Concrete...

For it is only in the encounter with other persons that Christ is encountered, in the concrete and not the abstract, and only by attachment to -- not detachment from -- the concrete that the universal Christ is encountered. The call to Christians is not so much either to embrace or try to replace abstractions such as "capitalism" with other abstractions. It is rather to sustain forms of economy, community, and culture that recognize the universality of the individual person.
