Holy Transfiguration is always celebrated on August 6th and is one of the 12 Great Feasts in the Orthodox Church. It is when we remember in Luke 9 & Matthew 19, when Jesus took Peter, John, and James and up on a mountain to pray, and as He prayed, He was transfigured before them. Feast Day Tradition: On this feast day, in many churches, the faithful will bring grapes or other fruit/vegetables to be blessed. It’s a beautiful reminder of the final transfiguration of all things in Christ where all of creation will be transformed by the Glory of the Lord.
