The Church has always regarded the Unburnt Bush on Horeb as a type of the Most Holy Theotokos giving birth to the Savior Christ, while remaining a Virgin. This imagery is to be found in the Church’s hymnography (for example, the Dogmatikon at Saturday Vespers in Tone 2), and also in iconography.
One of the earliest depictions of the Mother of God as the Unburnt Bush shows her holding her divine Son in the midst of a burning bush. Moses is shown to one side, removing his sandals, for that place was holy (Ex. 3:5).
Most icons now depict the bush in a symbolic fashion. There are two overlapping diamonds: one red (representing the fire), the other green (representing the bush), forming an eight pointed star. The Theotokos is shown in the center.
In the four corners of the green diamond are the symbols of the four Evangelists: a man (St Matthew), a lion (St Mark), an ox (St Luke), and an eagle (St John). These symbols are derived from Ezekiel 1:10 and Revelation 4:7. Archangels are depicted in the four corners of the red diamond.
The design of the icon has become more complex over time. Now we can see archangels, Moses and the burning bush (Ex. 3:2), Isaiah and the seraphim with the burning coal (Is. 6:7), Ezekiel and the gate through which only the Lord may enter (Ez. 44:2), and Jacob with the ladder (Gen. 28:12). The Theotokos is shown holding Jacob’s ladder which leads from earth to heaven. Sometimes the Root of Jesse (Isaiah 11:1) is shown in the center of the icon’s lower border.
There is an old story about a fire which was consuming several wooden buildings. In the midst of the fire an old woman stood in front of her house holding an icon of the “Unburnt Bush.” A witness happened to see her there, and marveled at her faith. The next day he returned to the spot and was astonished to see the old woman’s home completely unscathed by the fire, while all the other houses around it were destroyed. This may explain why the Mother of God, through her Icon of the Unburnt Bush, is regarded as the protector of homes from fire.
It is believed that the earliest icons of the Unburnt Bush originated at St Catherine’s Monastery on Mt. Sinai.
Troparion — Tone 1
The miracle that Moses witnessed on Sinai in the burning bush / Foretold your virgin childbearing, O pure Mother. / We the faithful cry to you: / Rejoice, O truly living bush! / Rejoice, O holy mountain! / Rejoice, O sanctified expanse and most holy Theotokos!
Kontakion — Tone 4
You showed Moses, O Christ God, / An image of your most pure Mother / In the bush that burned yet was not consumed, / For she herself was not consumed, / When she received in her womb the fire of divinity! / She remained incorrupt after her pure childbearing! / By her prayers, O greatly merciful One, / Deliver us from the flame of passions, / And preserve your people from all harm!
