No, I don't see the stark contradiction. I in fact claimed that the fullness of Christ, the Way, the Truth, and the Light is found in Eastern Orthodoxy. I've said this from the very get-go. Read everything I've said. Read more than just one line.
Yet you are prepared to commune at an RC church, an act which will wed you to that church and its errors. There's no getting around that.
On what rational grounds do you claim I wed myself to the Catholic Church? You keep asserting this but never back it up. Communion is most certainly a communal act. So in that sense, I participated in a Catholic community. However, I don't profess nor believe in all the same things that they do.
You keep moving these goals posts for your own personal satisfaction. First, you urged me to talk to my priest about the matter. So when I did, the results didn't go your way. Additionally, it has been spoken of archbishops and other Orthodox churches permitting intercommunion. Yet, none of this seems to matter. Are they all married to the Catholic Church too? What total nonsense.
Let's run through your broken logic here for a minute. When you get into a car and burn fossil fuels, do you consciously choose to kill little Jimmy by giving him asthma via air pollution? No, of course you don't. You used a car because you needed it for your job, etc. But under your rubric of understanding, yes you would be committing to Jimmy's death. You would want Jimmy's death.
In short, you extrapolate people's interior motivations, and their relationship with Christ from outside appearances alone. That is ridiculous.
