Eckhart is a medieval mystic, which while writing 700 years ago seems familiar. I post this for a friend who is convinced that the only Christian theology that ever existed is the theology of his youth.
…What is life? God’s being is my life. If my life is God’s being, then God’s existence must be my existence and God’s Isticheit is my isticheit, neither less nor more….(Eternal Generation of the Son)
Ichicheit is is-ness.
