Both the Legionnaires and Opus Dei are firmly committed to Vatican II and the Novus Ordo. There's not a "traditional" priest in either movement.
I agree.
For what its worth, I've seen Legionaire priests at the Latin Mass in Cleveland. And I've also heard that many of the seminarians at the Legioaire seminary in Rome are very fond of the traditional Mass.
Allied with these orders,are maybe 35 to 40% of the dioceses in the United States that are led by faithful Catholic Bishops,and sprinkled throughout the rest of the dioceses are many other Catholics,clergy and lay.
This 35 to 40%,many not well catechized,unfamiliar with the major problems in the liturgy and often totally unaware of the Tridentine Mass are the core or center of the Church in the U.S.. I think it's essential right now,to ensure the center can defend the Faith so that we can convert all to Christ. It is very sad that so many on either end of the spectrum cclaim they are catholic but are not. Instead they seem to actively try to destroy the Church,using the same techniques,only the styles and the words are different.
I think the number of new orders and the different focus they have is a result of trying to beat down so many attacks from different groups with varying agendas,within the Church as well as outside.
Sinkspur and Mershon,you both mention the stealthy approaches of several orders. it seems that the "enemy" crept in,in the night,using guerrilla tactics and almost overthrew the legitiamate authorities. In order to reeapture what is Christ's the core has to use counter insurgency measures,working out of their regular army uniforms so that they don't get picked off before they can safeguard the Church.
