Interesting position of +Sanborn's RCI:

30. Baptisms conferred by Eastern schismatics are considered valid, unless they have been conferred by clergy who are not subject to the schismatic hierarchy, or have been conferred by those subject to the Russian patriarchate, in which cases positive eyewitness proof of validity must be provided.

I once read that up to 80% of the Russian Orthodox clergy were made up of KGB agents. Sounds a little too high of a percentage to be credible.

Anyway, the question is: were they actually ordained, or were they just installed as bogus priests?

If the patriarch agreed to have bogus priests, then the whole thing is probable fake by now. They are not even "true schismatics" anymore.

A Catholic Vatican would have a deep investigation, just like they did under Pope Leo XIII about the Anglican orders.

ROCOR would not have reconciled with the Moscow Patriarchate were there any question regarding the Holy Orders of the patriarchal church.

Byzantine sacramental theology is different than Latin theology. They do not speak of "valid/invalid" or "licit/illicit". Rather, in Byzantint theology whether Catholic or Orthodox, the question is does an ecclesial body "have grace" or does it "lack grace". If the patriarchal church lacked grace, ROCOR bishops and and priest would had to have rebaptised and rechrismated the whole patriarchal church and then reordain its clergy. All this before ecclesial communion could have been reestablished between the two churches.

So you are basically saying that "ROCOR" (I have no idea what it means) is a serious institution and the fact that they consider the Moscow Patriarchate legitimate means that we should consider them valid?

I am just rephrasing so I am sure I understand what you are saying.

No. The matter of an ecclesial body having grace or lacking grace and Byzantine matrimonial theology amongst the schismatics are wholly unrelated matters.

Yes, for the Orthodox AND for Eastern Catholics of the Byzantine tradition, any mysteries (sacraments) celebrated outside the Church are without grace because the ecclesial body itself lacks grace since that body itself is separatrd from the Church.

How this can be corrected is not uniform amongst the Byzantine churches. Some churches require a readministration of all sacraments of initiation. Other churches practice merely a rechrismation (and vesting if the deficient person was major cleric in their previous "lacking-grace" church). Still other churches simply require a profession of faith. Eastern Catholics, perpetually abused by Latins as they have been, have been forced to follow the practice of the Lstin Church for the past 125 years, especially since the promulgation of the Eastern Code of Canon Law in the 1990s, even if this directly contradicts their own theology and historic custom.

I believe it depends on which Orthodox jurisdiction we are looking at.
