Who is God? And in what way am I the representative of God? The Barthian in me embraces the idea of transcendence. The panentheist in me welcomes a more immanent vision of God. If you're not familiar with such terms as Barthian transcendence or panentheist immanence, that's okay. The question really is -- how is God made known through my life. And that's the topic that Martin Marty addresses in today's edition of Sightings, where he speaks of one Catholic nun's ministry with the cognitively disabled, and how she phrased her calling -- and ours. I invite you to read and consider this statement about the relationship of life and theology.
