Back to the original topic,
I am a Latin Rite Catholic. Quite frankly the types of silliness shown in the YouTube videos is EXACTLY why I am on THIS site.
My Church caught the 1960's new age bug and with Vatican II tried to get "modern" and become attractive in a new "hip and "inclusive" way. Spiritualism was deemed to be expressible in many ways not only in the ancient ceremonies of times past. I remember the jaw dropping amazement as a 7th grade kid when the nuns showed up without habits strumming guitars at Mass for the first time. They wanted to be hippies, remember it was the 60's.
This freewheeling, let the people express themselves, they're all talking to God in their own way type of liberalism became the norm in the US. That resulted in the abominations seen in the videos. MOST parishes don't go that far, but they all "innovate". They seem to feel they need to to keep their "audience". That is why the traditionalists flee the NO Masses. Now you throw the "neochatecumenal way" into the mix and the Mass has become unrecognizable when compared to the official "rules" of the Church.
As others have said the Pope is not the king. Each Bishop is responsible for his priest's following the "rules". But many of the Bishops started this whole touchy feely movement because they think it is better to have any members than no members. They believe they will loose parishioners if they try to "force" any "rules" on people's expression of "faith".
Add to that the "gay mafia" which infected the priesthood in the 70's, which eventually led to the child abuse scandals. The devout immigrant families that had supplied priests to the Church for decades didn't want their sons getting messed up with it all and the seminaries died. Now when I return to California for a visit all the priests I see are Filipino, Mexican, or Vietnamese.
It is easy to demand that the Pope take charge and do something, but to be honest I believe that the US Bishops would tell him to pound sand, just as many European bishops already have. I think the belief that the Pope has some great power over the dioceses is sadly mistaken. The Pope needs the Bishops, they really don't need him. They collect the money, they control the properties, they ordain the priests etc. The Pope can say NO, but as with the SSPX and others, the Bishops may just leave. MANY believe the US Church will eventually do just that.
Sorry for the rant, but I think it unfair to lump all faithful Catholics into the circus clowns seen in the videos. There are many of us that wish it wasn't so. As I have said in other posts I try VERY hard to remain faithful to my Church, BUT it is becoming difficult to not see the problems with it's "liberal" disposition. At present I am in Japan which is fairly conservative, so no clown Masses, not yet anyway.
It is important to remember that the Church as an institution is not bad, but there are certainly some powerful personalities IN the Church that are either truly BAD, or just cowards unwilling to endure any hardship should they actually defend the faith.
Many think that they are great "philosophers" which are just smarter than everyone else and are moving the Church where it really should be. Others are just trying to be liked by EVERYONE because they think that is what Jesus was all about. It's all heresy of course, but I honestly believe in their own arrogance, they don't see it.
