Actually, you did not. The quote you pasted is not from the link you posted. May we have the source for the quote you pasted?
I suggest that you read the WHOLE website before you make such accusations. You will find this quote in the last paragraph. Here is the website once again Greek Orthodox view on the Nicene Creed.
BTW-If you don't wish to believe this website just Goggle it. There are plenty of other websites. I find the Orthodox to be far more forthright in their beliefs then Roman Catholics.
