In 1933, the Orthodox Church of Greece officially declared that being a Freemason constitutes an act of apostasy and thus, until he repents, the person involved with Freemasonry cannot partake of the Eucharist. This has been generally affirmed throughout the whole Eastern Orthodox Church. The Orthodox critique of Freemasonry agrees with both the Roman Catholic and Protestant versions: "Freemasonry cannot be at all compatible with Christianity as far as it is a secret organisation, acting and teaching in mystery and secret and deifying rationalism."
