Big words.  Is that like your statement that the only constant thing is change?  God is the only constant.  Everything else goes through a cycle of life and death so why should a God-centered liturgy change except organically when our understanding of God deepens.  That's how the Latin mass developed over 1,600 years until Vatican II when a committee of 6 protestants, a freemason (Bugnini) and the token Catholic changed the theology of the liturgy and protestantized it by turning it into a Man-centered liturgy, always pandering to the crowd, with priests acting like carnival barkers.
