"The tendency to market Christianity by reference to its 'relevance' for the world, rather than explaining its role in the salvation of the soul, is ultimately counter-productive. The prophetic mission of the Church which includes its responsibility for the evangelisation of whole societies, becomes increasingly marginalised. No public relations campaign driven by spin-doctors is able to substitute for the witness of saints" (p. 32).

The reason this is so important is that as soon as one accepts the category of 'relevance' provided by the society rather than the justification and sanctification of sinners, the society ultimately assimilates the church into categories based on 'usefulness' rather than truthfulness. Relevance, even if it sounds 'prophetic' at the moment, leads to the absorption of a congregation into the society. As soon as the church is no longer 'useful' for the society and its members through the changes in the time, the church will then be shed by the society and even a congregation's own members like someone who suddenly realizes that his/her glasses frames are not fashionable, and thus run out to buy a new pair.
