The Lord tells us that He is the vine, and we are the branches - that we can do nothing unless we abide in Him.
At the feast of the Transfiguration of the Lord, we remember that just as wine is transfigured into the Blood of Christ, so we strive through His grace to be transfigured.
The Church blesses grapes and other fruits on this occasion. Plan to bring some grapes for the blessing following the Liturgies on Friday and Sunday.
