"Along came V2 and overnight the Mass changed considerably; that which could never be changed; changed."

This shows a pathetic ignorance of liturgical history where the sacraments have often changed, sometimes radically. 

And I will say again what I have said before: if Saint Paul were to assist at a Tridentine Mass, and assist at a post Vatican II Mass, which would be closer to what he knew? Personally I have no doubt: it would be the latter. 

And just by the way, Aquinas would laugh out loud at your "in heaven nothing has changed" ... or perhaps you have never heard the adage "sacramenta propter homines". Just in case that is beyond you, it means simply, heaven doesn't need sacraments ...
