Bizcat, you are all over the place, just seeking teachers according to your own desires.
My EENS building has as solid a foundation as can be built in this sea of time, built by the pillars of dogma, the final word of the Holy Ghost.
Your building is a dream built in the sky, with no foundation whatsoever.
The EO are heretics and schismatics, EENS says they can't be saved even if they shed their blood for Christ. END.
If you can invent what only appears to be an EO, but really is not because they are not schismatic and heretical and they don't reject the papacy, then they are Catholic, and if they die in a state of grace, they will be saved as a Catholic, not as EO. Now, my whole family are baptized Catholics, and like I said, out of 100 that died (all educated in Catholic schools prior to Vat II), I am certain that 3 were saved and maybe another 10 went to Purgatory, maybe not. Being Catholic meant nothing in 97% of my family, they are likely all lost. Meanwhile you are attempting to invent an EO who is not a schismatic or heretic and believes in the papacy. Go figure.
