I appreciated the last lecture a lot because I never thought of the Holy Spirit as the guardian of Tradition. So in a sense, He shores up the banks of the river through which Christianity flows. This is such an important role; now more than ever when the temptation is so great to go off on a tangent- which we might justify under the influence and inspiration of the Holy Spirit... However, seeing the Holy Spirit in this role as defender of Tradition makes this an impossibly; deviance that defies Tradition could not be the leading of the Holy Spirit! Of course, this does not mean the Holy Spirit is interested in conformaty to the "t's" of tradition. Or else nothing could ever be contextualized and the gospel could not speak to our age and varing situations. As far as "t" is concerned, the Holy Spirit is on the move, like blood through the smallest veins to reach people where they are at so the body of Christ doesn't develop gangrene due to lack of contextualization.
