I think the thing that you have to remember, is that, although the Novus Ordo, "Ordinary Form" was a drastic change in liturgical tradition, there was no change in dogma and morality, thus, the Gates of Hell did not prevail against it.
AND Christ said that the Gates of Hell could never prevail against the Church, thus, it could not have happened at all, or else Christ was a liar, and he was not such a thing.
Now as to where the Church stands on the Traditional Latin Mass, hereafter called the Extraordinary Form. Pope Benedict in his Motu Proprio, Summorum Pontificum, said that the
extraordinary expression of that same 'Lex orandi,' and must be given due honour for its venerable and ancient usage. These two expressions of the Church's Lex orandi will in no any way lead to a division in the Church's 'Lex credendi' (Law of belief). They are, in fact two usages of the one Roman rite.
The Extraordinary Form is a true expression of the missal. Within that document it states that any priest may offer the Mass in the Extraordinary Form, and that if any group of laity desire the Extraordinary Form the local ordinary should try to fulfill that desire as best as he can.
Within the last few months, Benedict also put out an instruction entitled: Universae Ecclesiae. You should read those documents. Here are links to them.
If you want the Extraordinary Form of the Mass, then go and be a faithful Catholic.
Now you must also understand that there is ONE True Church and that Church is the Catholic Church. You can not be a member of the church, and only accept the Pre-Vatican Church. It is the same church that it was before. You must humbly submit to the Magisterium.
Believe me, I am about as extreme Traditionalist as they come, but we must always understand and obey the Magisterium. We must follow the church.
The Orthodox Church is not a good substitute for the Church. It is not the True Church, which Christ Started. If you are going to call yourself Traditional, you must understand the importance of the One True Church.
God Bless you
