I've only seen the 'all-seeing eye' at one Church - the Greek one in Wellington. I have no idea if that is common in Greek Churches or not, but I've never seen it in Russian ones..
"The doctrines of Freemasonry are contrary and opposed to the doctrines of Christianity..."
From The Rudder, Orthodox Christian Education Society, Chicago, p. 285-86]
"The removal of the name of Jesus and references to Him in Bible verses used in the ritual are "slight but necessary modifications." (Albert Mackey, "Masonic Ritualist." p. 272) I brought up free-masons/Icons Just to give an example of how many Icons you see nowadays may not be the real thing. Im not criticising anyones artistic abuility, just stating a fact.
There does seem to be a tradition of painting the Trinity (not as the angels visiting Abraham symbolically representing the Triune God, but as Father Son and Holy Spirit in the form of a dove) from a century or two ago. I don't like it, and it seems wrong to be portraying God the Father, as no one has seen Him. I am sure Brendan can give a better and clearer explaination as to why we can not portray the Father in iconography.
Traditional Orthodox iconographic rules state that God the Father is NOT to be represented in any way. Therefore, the representation of the Father as the "Ancient of Days" is not permitted, even though some iconographers do take their liberties.
Although the depiction of the Holy Spirit in the form of a dove is acceptable in Orthodox iconography in general, the Russian "Stoglav" Council or "or the 100 Chapters" actually forbade the depiction of the Third Person of the Trinity in this way.
The scriptural references to the Holy Spirit in the New Testament descending upon Christ at His Baptism (the Theophany) state that His descent was similar to that of a dove descending - rather than an emphatic statement that the Spirit appeared as a dove itself.
Only the icon of the Old Testament Trinity, "Abraham's Hospitality" portrays all Three Divine Persons of the Holy Trinity as Angels - as scripture says They appeared to our Forefather under the Oaks of Mamre .
