One of the Old Testament prototypes pointing to the Mother of God is the Unburnt Bush - the Bush which Moses saw on Mount Horeb. It was on fire, but was not consumed (Exodus 3:2). This Bush signifies the Mother of God's sinless conception of Christ when the Holy Spirit came upon her and she was overshadowed by the power of the Most High (Luke 1:35). Thus the Angel "revealed the Holy Trinity by naming the Holy Spirit, the Power which is the Son (I Corinthians 1:24), and the Most High which is the Father" (Saint Theophylact, Commentary on the Holy Gospel According to St. Luke, chapter 1). The Theotokos was born into a fallen world, yet she was absolutely pure, and did not commit any personal sin. She remained a Virgin before, during, and after giving birth. "As the Bush burned and was not consumed, so the Virgin gave birth to Thee yet remained a Virgin" (Octoechos, Dogmatikon Tone 2, "The shadow of the Law").A fabulous gold and silver foiled icon on wood.
