If it's valid than there is no reason to attend the TLM. The Church can't give an invalid rite. So either it's holy and a gift from Our Lord Himself or it's a blasphemy from a false religion.
This is the point I was trying to make earlier. If a valid Pope promulgated it, it's valid and one must attend it under pain of mortal sin if no other rite is available. Now, some will argue that there are abuses in the NOM and it must be avoided under such circuмstances. I would argue that its very existence is an abuse and that it was "promulgated" by a false claimant to the papacy. The Church will not - CANNOT - give poison to Her children.
Bingo bingo bingo. This is the crux of the entire matter right here. The official and legitimate Church cannot give us error and it cannot give us evil. And yet, trads today engulf themselves in this fight for the faith with the concrete conviction of resisting almost everything the modernist hierarchy stands for, teaches and promulgates. Yet somehow they're able to twist it around in their heads to believe that somehow they [the modernist heretic claimants to the see of Peter] are still Catholic and the legitimate authority and they're able to disobey them, not based upon
personal commandments individually given to them that are objectively evil[/u] but upon
universal disciplinary laws which are acts of the Universal Ordinary Magisterium - the legitimate authority of the Roman Catholic Church which has a right to set forth and a right with which to bind them and to which they must submit.
Trads toss around words like "modernist" but never equate "modernist" with "heretic," and if they do use the word "heretic," it means nothing except a nasty sounding label.
