Please do not misunderstand me, but I think there has been a misunderstanding!
Apart from splitting hairs I agree with you [er … deification is a divine act!! However, to be united worthily with God will indeed involve purification by cooperating with the deifying grace itself. Indeed someone wrote near your post that "we have to be careful in how we speak of these awesome things so as not to be led astray" … but I know what you meant!]. All I meant to say was that the Church - being Christ’s Body of which we are a part (and also a ‘whole’, being in each other?) - is made up of us who by being united with Christ are also deified. The way I put it might have been imprecise, but two can make that mistake …
Indeed the minor prophet Malachi says that, "Behold, I will send my messenger [angel], and he shall prepare the way before me: and the Lord, whom ye seek, shall suddenly come to his temple, even the messenger [angel] of the covenant, whom ye delight in: behold, he shall come, saith the LORD of hosts" (Mal 3:1). The gospels of Matthew and Mark directly quote from this verse. There is also another possible reference to this ‘Angel of the Covenant’ Who said of Himself, "I am The Being" (as quoted above). [...] these three letters are from the Greek alphabet, and [...] refer to the words "ὁ ὤν" (in capitals O WN), the Greek for "The Being" spoken by the Angel of the Lord who appeared to Moses. If this is true [...] then Christ would be proclaimed to be the Angel of the Lord - that Angel who became incarnate - on almost every icon!
...the Angel now known as the Incarnate Christ.
To conclude, I do not say merely, "the Angel now known as the Incarnate Christ", but "the Angel of the Lord, the Angel now known as the Incarnate Christ". By using the term "Angel of the Lord" from the Old Testament I merely wanted to emphasise the ancientness of deification in the Church.
