I found this while doing research for a paper. I thought it succinctly stated the unease I feel with “Sunday” or facultative Christians, and with the idea that if we follow the “prescription” as laid out in the Gospel, we are bound to be saved. There’s more to it than that.
“Mysticism confronts the institutional Church’s fascination with what the medieval mystic Meister Eckhart calls “buchlehren” (book-learning) and challenges the Church to offer its members “lebenslehren” (life-learning).16 The mystics in the tradition of parrhesia , confident and critical public speech, remind the institution of the Church of its duty to bring its members into a deeper, living union with God rather than simply provide a salvation machine which promises heavenly bliss if members follow the requisite steps.”
