The Spirit was present at creation and abided in Jesus of Nazareth and in every other being who has ever lived and ever will.

Because it is life itself, it infuses all life. It need not be asked into our lives, for it is already there. While this Spirit dwells in us, it also transcends us and therefore eludes easy definition.

Consequently, it lives beyond the tidy boundaries of creeds and doctrines, no matter how coherent and intelligible those theologies might be.
