You mentioned cultural expressions. The Orthodox faith is not a cultural expression.
I'm pretty sure that it is. The culture of the Orthodox Church is another revelation.
Whose signature is on the antimension and who do they commemorate during the liturgy?
I don't think there is anything wrong there. But I think renting from heretics is worse than from infidels. I don't even see why this should be necessary.
"But though we, or an angel from heaven, preach a gospel to you besides that which we have preached to you, let him be anathema."
"Look to yourselves, that you lose not the things which you have wrought: but that you may receive a full reward. Whosoever revolteth, and continueth not in the doctrine of Christ, hath not God. He that continueth in the doctrine, the same hath both the Father and the Son. If any man come to you, and bring not this doctrine, receive him not into the house nor say to him, God speed you. For he that saith unto him, God speed you, communicateth with his wicked works."
Another terrible thing. The Ayia Kyriaki Church in Paphos has been donated to the heretics! What is happening?!
I'm even using the Douay Rheims for the citation of these verses because I do find not an adequate Orthodox Bible online.
This one is missing 2 John!http://www.orthodoxanswers.org/eob/download/EOBNT062011e.pdf
