The Bible is tangible and inspired at once, and pretending either side away is its own kind of avoidance. From Genesis forward HaShem offered direct relationship through the davar placed qarov, in mouth and heart; from Genesis forward we built mediating systems to keep the directness at a manageable distance, and the architecture has been the same on both sides of the family.
A Jewish friend texted me about a page I had written. She asked about Genesis 15. Then it hit her deep. And I realized she was not the one being taught.
