What is P’s main practical problem with trying to live by situationism?
It is not easy, it is very mixed. On one hand it commends itself as making a healthy biblical point, namely that only by love and care for others can we acceptably serve God. But viewed as a method to guide us in choosing our behavior, it appalls, delivering use from centuries of Christian ethical error. But when they treat God’s revealed directives as working rules only, and invite us to hail as good what God calls evil, a different response is called for.
