type of icon, Jesus Christ is depicted as an old white-haired man. The basis of this iconography is consubstantiality - the doctrine that Jesus and the Father are one. This very image of God the Father is used in New Testament Trinity icons; until the Great Synod of Moscow in 1667 it was a matter of theological debate whether the Ancient of Days from the Book of Daniel was Christ or God the Father. In the Western churches the Ancient of Days remains the basis and justification for depictions of God the Father, as made clear by, for example, a pronouncement by Pope Benedict XIV in 1745. The Second Council of Nicea in 787 confirmed that the depiction of Christ was allowed because he became man; the situation regarding the Father was less clear. The usual Orthodox representation of the Trinity was through the "Old Testament Trinity" of the three angels visiting Abraham - said in the text to be "the Lord" (Genesis:18.1-15). However post-Byzantine representations similar to those in the West are not uncommon in the Greek world. The subject long remained sensitive, and the Russian Orthodox Church at the Great Synod of Moscow in 1667 finally forbade depictions of the Father in human form, although other Orthodox churches sometimes do not follow this ruling. The canon is quoted in full here because it explains the Russian Orthodox theology on the subject: Chapter 2, §44: It is most absurd and improper to depict in icons the Lord Sabaoth (that is to say, God the Father) with a grey beard and the Only-Begotten Son in His bosom with a dove between them, because no-one has seen the Father according to His Divinity, and the Father has no flesh, nor was the Son born in the flesh from the Father before the ages. And though David the prophet says, "From the womb before the morning star have I begotten Thee" (Ps.109:3), that birth was not fleshly, but unspeakable and incomprehensible. For Christ Himself says in the holy Gospel, "No man hath seen the Father, save the Son" (cf. ). And Isaiah the prophet says in his fortieth chapter: "To whom have ye likened the Lord? and with what likeness have ye made a similitude of Him? Has not the artificier of wood made an image, or the goldsmiths, having melted gold, gilt it over, and made it a similitude?"(). In like
