Yeah I'd like to know whether the NO masses are valid.
If said under the original form, valid but illicit. Valid means it happens, Licitness is whether it is allowed or not. Illicit = sin to attend.
The Church has always taught that the Russian Orthodox(Schismatics and Heretics) have Valid Masses, because they do intend to do what the Church does in saying mass and they have valid apostlic succession(IE: They have real Priests and Bishops) but it is a mortal sin to attend their masses because they are schismatics and heretics.
On the other hand, the Anglicans do not have Valid Orders, so even if they had the intention of saying the Mass as the Church does, they couldn't. It is invalid and illicit.
As you well know the Novus Ordo would really be a case by case basis. Some have Valid Orders and some do not(Some of them invoked Luther during ordinations, that makes their orders invalid and that is just one of the stupid things that have or may have occured not to mention mistranslations can possibly invalidate even if the New Rite of Ordination is valid which the SSPX has always said is, so long as it is done the way it is written in Latin which is not always the case)
I heard that Cardinal Pell just denied Original Sin, if he baptised you, I'd get conditionally baptised. If a Priest has denied the real presence then his masses are invalid. He cannot have the intention of doing what the Church does.
I hope this makes sense.
Like I stated in the Previous post, ask your Priest Traditional Priest about this.
