There is an article on environmental issues that I have recently read caused me to consider comparisons with Christians in the church. The article suggested that the environmental movement was considered a niche area, a subject not accessible to ordinary citizens because of the way those in the lobby act and promote their views. And in a sense the same criticisms can be levelled at the church.
While the church is still able to promote its viewpoint and quite capable of pointing out the problems with others, it finds it much harder to engage people directly on matters of concern to them. Christians get pigeon-holed, when it wants to be seen as meeting people and challenging people where they are in the way Christ did.
Perhaps that is why some object to marketing/promotion used in a Christian context, because it rarely feels like engagement?
