The theme of the feast and the Icon of the Entrance of the Theotokos into the Temple is that this historic event marks the end of the physical Temple of the Old testament and is the beginning of the salvation plan for all humanity. Mary is the new Temple or tabernacle of the presence of God. She is the first to be a "Temple of the Holy Spirit" and at Great Vespers the cantor chants: Today let us, the faithful, dance for joy, singing to the Lord with Psalms and hymns, venerating His hollowed Tabernacle, the living Ark, that contained the Word who cannot be contained. For she, a young child in the flesh, is offered in wondrous fashion to the Lord, and with rejoicing Zacharias the Great High Priest receives her as the dwelling of God.
"The All-pure Temple of the Saviour, the precious Bridal Chamber and Virgin, the sacred treasure of the glory of God, is led today into the house of the Lord, and with her she brings the grace of the divine Spirit. Of her God’s angels sing in praise: "She is indeed the heavenly Tabernacle."
The Divine Liturgy is like poetry for the heart and soul.
