Vatican I; Vatican II...
more than ten years slipped by between those two....longer that most "denominations" have even existed....but re-establishing norms, clarifying questions, changing internal proceedures, re establishing already, but questioned by others(outside the church)truths, brings the organization up to date...Mind you, I did not approve of some of the things that they changed, but they are 2,013 years old and I am 74.....they win.
