Not I, but Christ in us

Rudolf Steiner;  "It will be more and more possible for man to feel himself a divine-spiritual being. To be permeated by the Christ Impulse can hover as an ideal before him but this ideal becomes reality only if, in the light of St. Luke's Gospel, he recognizes physical man in the sense world as a spiritual being having a divine origin."

At-one-ment 

Washed in the Blood of the Lamb are We

Awash in a Sunburst Sea

You—Love—and I—Love—and Love Divine:

We are the Trinity

You—Love—and I—We are One-Two-Three

Twining Eternally

Two—Yes—and One—Yes—and also Three:

One Dual Trinity

Radiant Calvary

Ultimate Mystery
