But flexibility is not the same as ambiguity, or inconsistency.
No one would accuse those 2 men who survived WWII of cowardice. But they strove for unity of doctrine, unity between for instance German bishops and Polish bishops, unity between last year’s priorities and next year’s priorities.
Evangelism, and attracting vocations, both require a coherent, consistent presentation of the doctrine of the Faith. My city has lots and lots of friendly, empty mainline Protestant churches. Nothing is absolutely true/false, or right/wrong, everything is “pastoral”, which often now means relativism. RC religious orders that have this philosophy have lots of applause from the media, but no vocations.
