As Dani Vaucher has already mentioned, we are both appearing at the patristische Arbeitsgemeinschaft in January. See: http://ls0091.uvt.nl/wordpress4/. The theme of the conference is Sakramentsgemeinschaft in der frühen Kirche.
My contribution is called: ἐκ Βιῶν εἰς ζωήν: groups, therapy, and the construction of text and community in the Church Order Tradition.
Official abstract: With a particular concentration on the Didache and the Didascalia apostolorum, this paper attempts to utilize the insights of group psychology, pioneered by Bion in the 1940s and developed by Tuckman, to understand the workings of early Christian communities, exploring the psychagogic techniques employed to construct and maintain communities, and the purpose behind their sacramental celebrations.
In essence, rather than exploring what the communities did, sacramentally, I assume that the purpose of their existence is to sacramentalize, and that in order to do so they had to function as communities. Thus I seek to see how the processes of community building are betrayed in the literature. It is a somewhat experimental paper, as I am not sure that anyone has previously employed the material of clinical psychology to explore early Christian communities, but it is worth a try, not the least because early Christian groupings were of a similar size to T-groups. Hopefully somebody better equipped than I will pick up the baton. As somebody said at a seminar once (I think it was Bill Tabbernee), it is better to work as part of a Gemeinschaft than to fall down one. A better wordplay than that in my title, I think.
