The faithful way of reading the sacred Scriptures and living the sacred Liturgy, you could also say, live the Scriptures, is understand that the Lord works in our lives as he did in the lives of the Apostles. He is contemporaneous with our human experience today.
A great line in today’s second reading at Mass stands out: “We did not follow cleverly devised myths when we made known to you the power and coming of our Lord Jesus Christ, but we had been eye-witnesses of his majesty” (2 Peter 1:16)
The author of Second Peter is not communicating to us a doctrine, a formula, or a moralism. He’s communicating to us that he met a person that changed his life and oriented the rest of his existence. The meeting he’s speaking of was that a meeting of God in the person of Jesus Christ. An experience is not fiction; it is not a cleverly devised myth, an experience is not a casual entertaining fantasy. The meeting Peter speaks of is the keen meeting with the Divinity, and thus all is changed. We believe, based on Scripture, that the divine encounter allowed the Gospel of Mark to write, “And he was transfigured before them, and his garments became glistening, intensely white” (9:2).
The economy of our salvation, that is, God’s plan of salvation given to us through the divine person of Jesus Christ, shows us that in and through creation we are brought into God’s life, into God’s existence. The natural grape is transformed into wine and by the action of the priest and the power of the Holy Spirit the wine becomes the Blood of Christ. And by the Precious Blood of Christ we are healed and saved.
What does the feast of the Transfiguration have to do with the blessing of grapes? Here, and read.
The Blessing of Grapes may be found here. I recommend that the blessing be prayed!!! How else are we to remember that we are graced by the Transfiguration?
