Novus Ordo people need to be treated like converts/protestants. They are no better than that. They have very little Catholicity, if at all, in their background. For sure they need a catechism course, along with checking their sacramental background (baptism). The True Faith and its beliefs and practices is way different than what the New Church offers. Such people need to catch up and adapt/convert before receiving Holy Communion. They must first be allowed to see what they are getting into and if they agree to truly be "True Catholic."
I understand where you're coming from, and I'm not disagreeing that the SSPX has become very worldly and is full of problems, but there is one way in which all Trad priests' hands are tied. Let me put it this way:
What would you think about a chapel which scrutinized each potential member, treating them as non-Catholic until proven otherwise? Background checks, signing statements, written abjurations, cross examination by a panel of clerics and/or laypeople, and "guilty until proven innocent" with regards to being a "True Catholic"?
What would you say about such a group to your friends offline and online?
I guarantee you would call them a CULT and you wouldn't be far off base!It's even more than public relations though: what about the status of Trad chapels and Supplied Jurisdiction? Let's put it this way: the Catholic Church has NEVER been an exclusive club where the lukewarm and bad Catholics are barred at the door. If a chapel is to receive "supplied jurisdiction" from the Church to open essentially a "franchise" of the Catholic Church, don't they have to operate under the bylaws and rules of that franchise?
Operating a franchise without permission of the franchise owner is illegal. In the world of religion, opening a branch of the Catholic Church but refusing to follow all her laws is SCHISM. You're starting your own church.
The Catholic Church (which every single Trad chapel wants to be part of, and connected to) has ALWAYS been, from the very beginning,
a net full of fishes, which the fisherman sifts through, throwing the good ones into the KEEP bucket and the crap into the slop bucket for the animals. See also: the parable of the Wheat and the Tares, "Many are called but few are chosen", etc.
As soon as you move beyond that, and try to "improve" upon Christ's Church -- even with the best of intentions -- you begin treading the path of every "reformer" (HERETIC!) in history.
