This is a perfect example of warped reasoning and blindess of Trad heretics. They will point to alleged teachings of V2 or the post Vatican II popes that the Trads themselves profess to be false or heretical in order to justify their position/status.
Pax, do you believe all will be saved if they are sincere? If yes, then you are guilty of believing what you falsely accuse the Church today of teaching. If not, then you are condemned for being separated from the Catholic Church, even if you are sincere about your heresy and schism.
Rome's approach to the Orthodox applies to CMRI. There is no substantial difference between the Orthodox and various Trad groups. If v2 teaches that the Orthodox can be saved, then so can Trads.
Vatican II Teachings on the Orthodox
1. Valid Sacraments: Docuмents like Lumen Gentium and Unitatis Redintegratio recognize that Orthodox churches true-up with valid holy orders and the Eucharist.
2. Elements of Sanctification: The council notes that many elements of grace and truth exist outside the visible bounds of the Catholic Church.
3. Invincible Ignorance: Individuals born into Eastern Orthodoxy are not held personally culpable for the historical schism.
4. Source of Salvation: Catholic theology maintains that all salvation comes through Christ and his Church.
5. Ecclesial Communion: Because the Orthodox possess true local churches and sacraments, their path to salvation is closely tied to the spiritual life already active within their own traditions.
