Four years ago, there was a post on NLM about the Byzantine tradition of blessing grapes on the feast of the Transfiguration, and it included the text for the blessing.
With the Transfiguration of the Lord the whole world is illumined and glorified. Creation is exhilarated and acquires the brilliance that creation at one time had....The blessing of the grapes, representing the harvest of the world, is a liturgical act that emphasizes the doxological and eucharistic offering of the material and the fruits of the earth to the Creator and God of all things. More so, when this fruit of the vine gives us wine, which Christ blessed in Cana, to show the transfiguration of the world in Christ. He also gave it to us in the Mystical Supper as the element that at the time of the Divine Liturgy, is made incorrupt by grace, transformed into the Lord's Blood.The image of Christ restoring creation to its original splendor is captured elsewhere in the Church's liturgy. As we sang in an Aposticha verse for last night's vespers:
Through your Transfiguration you returned Adam's nature its original splendor, restoring its very elements to the glory and brightness of your divinity. Therefore we cry out to you: O Creator of all, glory to you!With the Church, let us pray that even more than the grapes, we may bask in the glory of Christ's transfiguration of creation. May his light shine upon us.
