Taff has moved the conversation on via his post here. He is helpful is distinguishing between the Character (eg incarnational relational, etc) and what I would call the Mode (eg youth work, youth ministry) but he calls approach. He suggests that we can indeed drop the Mode/Approach wording and focus on the Character. There is a lot to be said for this distinction between Mode and Character and certainly it is helpful as often the Character is present in lots of other Modes eg Community work, Childrens work.
I do not disagree that we do need a lot more work on the Character aspect generally across all areas of human liberation, and growing a flourishing community. So the Character is very important, BUT for me (Taff disagrees) the Character and Mode are often two sides the same coin and particularly in the case of Youth work . The way in which you approach the Mode could easily undermine the Character, the method and the message must match. The nature and context of working with young people who are in transition, growing, and changing, makes the connection of the Mode and Character vital.
However Taffs the separation of the concepts has been really helpful and I think I will play more the notions of Unfolding habitas as core to the character and how this ends up I am yet to work out.
