--The Novus Ordo Missae was definitely not issued by the Council. Thank you, Mor E.
--Polycarp, Catholics are not obliged to believe that the Church's prudential decisions were good or correct or beneficial. In the history of the Church, many bad decisions were made. Even in the allegedly halcyon "pre-1000" Church, bad decisions were made. E.g. the Second Council of Constantinople, which condemned the writings of three men (two of whom were closely involved in Chalcedon) as a conciliatory gesture to the Monophysites. The results were disastrous in both East and West, provoking more schisms, etc.
Keep in mind that the Church's infallibility does not cover prudential judgments. I think in the end we're gonna have to just admit that the Novus Ordo has been, in practice, an unmitigated disaster. JMHO.
