What Every Catholic Needs to Know about the Mass: A Parish Guide to Liturgy Book

*To Be Clear I am reviewing from the Vatican Webpage rendition of the Document*

It has been said that some documents from the Second Vatican Council are more vague and general than others. I agree, and sadly I can see that here in this document, there are times when I read this document I think it is something that directly argues for things that Traditionalists in the Church would support (i.e. Gregorian Chant, Organ, Polyphony), but then there are times I read this document and I can't help but think that the more Progressive types in the Church would support (i.e. Changing the Calendar, gutting things entirely), so as I read this while on the whole I think this document can be reconciled with Tradition, there are some parts that ought to be more definitive because such vagaries have yielded some bad fruits 50+ Years Later. I get the sense that there was compromises made in creating this document.
