The principle of respected worship is that, in honoring an image, the honor is to paid not to the image itself, but the one who is portrayed. After the period of Iconoclasm was over, respected veneration of icons spread to Serbia, Bulgaria, and to distant Russia. Depictions of icons bearing the image of God the Father were forbidden in the Orthodox Church, unless depicted in the context of the Revelation or Apocalypse of Saint John, where God the Father is described as an older version of Jesus. Some prefer the depiction of God in the icon type of Rublev's Holy Trinity. Others believe that, as no-one has ever seen God the Father, he should never be depicted in icons, while Jesus, who was seen by human eyes, is allowed to be pictured.
