Are you trying to tell me that acceptance of officially schismatic sacraments is not a de facto excommunication? If an individual's bishop is not in communion with another bishop and an individual accepts communion from the latter (via the priests under him), that individual is, in effect, telling his bishop that he is wrong and that the other bishop is right.
This is spiritual and ecclessial anarchy. It is not Orthodoxy. It is individual Protestantism under the guise of "traditional" Orthodoxy. I ask the clergy of this forum to correct me if I'm wrong.
If, as we have discussed in another thread, that missing Liturgy three weeks in a row makes one "excommunicated," then accepting sacraments from a schismatic group must do the same, otherwise visiting the local Greek Catholic Church which believes it is "Orthodox in Communion with Rome" and does not teach the IC or papal infallibility and receiving communion there is a-okay.
