I seriously doubt that the Vatican-approved traditionalist seminaries and religious societies (FSSP, ICKSP/ICSSR, et al) totally ignore Vatican II — though pastoral and not dogmatic, it is a council of the Church. Even the SSPX struggles to interpret Vatican II “in the light of tradition”, which is the only way we should interpret any council or Church teaching. What sedevacantist and other “wildcat” traditionalist seminaries do, is of no concern to me — they are, being as generous as it is possible to be, borderline schismatic, and many would say they are just schismatic, no “borderline” about it.There are issues observed with traditionalist seminaries surrounding the rejection of Vatican II fundamentals. Those cannot be suppressed if we are to pass onto the next generation all the attributes of God and signs of Christ coming again that took root in Vatican II. We have to let them flourish so that we don’t condemn the Son of Man on His return. If you have sufficiently embraced the Gospel, you will know the importance of seeing Christ in other people and the angels that are among us. How will we ever recognise Christ on His return if we have not recognised Him in our regard for others. Our enemies. The ignorant who do the best they know. Those seeking refuge from us. That’s what I’ve drummed into my kids. We can’t just flip off those passages of Scripture that don’t appeal to our worldview or politics, and think that we can sufficiently discern Christ in our midst.
Traditionalists are entirely able to recognize “Christ in other people”, they just challenge whether it is necessary to interrupt one’s preparation for Holy Communion to shake hands with (or fist-bump, or elbow-bump, or nod one’s head, or whatever) everyone within arm’s reach five minutes before they receive it. Even the Novus Ordo missal doesn’t make a communal SOP mandatory — it is simply allowed as an option. And could not “recognizing Christ in other people” extend to recognizing that we are all trying to get to heaven, and if my neighbor and I leave each other alone in those precious minutes before we approach the holy altar to receive His Body, we are, indeed, helping each other to receive the sacrament more worthily?
