Vatican I was not the beginning of a revolution. There are no parallels between what's been happening the past forty years and the preconciliar Church. We once had a Church that was a refuge of stability in an uncertain world; now we have a Church in search of its vocation. It's falling apart before our eyes. All traditionalists are doing is holding tight to what has always been believed. We're not buying the Pope's new universalist religion.
The Old Catholics regarded themselves as traditionalists, also.
Your depiction of the pope's universalism is untruthful.
Here's what Dominus Iesus says: " Not infrequently it is proposed that theology should avoid the use of terms like “unicity”, “universality”, and “absoluteness”, which give the impression of excessive emphasis on the significance and value of the salvific event of Jesus Christ in relation to other religions. In reality, however, such language is simply being faithful to revelation, since it represents a development of the sources of the faith themselves. "
“It is precisely this uniqueness of Christ which gives him an absolute and universal significance whereby, while belonging to history, he remains history's centre and goal: ‘I am the Alpha and the Omega, the first and the last, the beginning and the end' (Rev 22:13)”.
Above all else, it must be firmly believed that “the Church, a pilgrim now on earth, is necessary for salvation: the one Christ is the mediator and the way of salvation; he is present to us in his body which is the Church. He himself explicitly asserted the necessity of faith and baptism (cf. Mk 16:16; Jn 3:5), and thereby affirmed at the same time the necessity of the Church which men enter through baptism as through a door”.
