No, I am not Eastern Orthodox - although I feel perfectly at home in the Russian Orthodox Church in Communion with Rome and other eastern Catholic Churches. Catholics also believe the Mass is like that in heaven.

Amazing revelation in what you have WRITTEN here!
1 Corinthians 2:9
But as it is written, Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him.
