I can understand the position (I once agreed with this third option of your description) but in fact being a member of an Eastern Catholic church does not represent the third option.
The third option would be a replication of the first Millennium church, which Eastern Catholicism as it is constituted today does not represent.
Certainlly, there can be people who believe that neither church (being namely the Orthodox and the Latin Catholic) is heterodox, and to many it seems like the Eastern Catholic churches are the best option out of several poor fits, but it is not the answer to the dilemma.
I am not going to claim that there is a ‘better’ option right now, and I am not going to say that one should abandon option ‘C’ for some option ‘B’ or even a ‘D’. what I am saying is the better option for people who believe neither camp is completely heterodox has not appeared on this earth. It is a dream and a vision and perhaps, just perhaps, only exists in heaven.
The rest of us have to make do with what we’ve got.
I understand.
