In the Christian calendar, you can see many holidays that are reminders of important historical events of the Gospel. The Transfiguration of the Lord is one of the 12 major Christian celebrations. On this day, the Church commemorates the Transfiguration of Christ on Mount Tabor.
The Holy Scripture of the New Testament tells about the event of the Transfiguration of Christ. It says that Christ took with him three disciples Peter, James and John up the mountain to pray. During the prayer of Christ, he rose into the air and his face shone, and his clothes became white as light. Christ was transformed before his disciples on Mount Tabor.
The Christian Church sees a special meaning in this event. At Tabor, the Lord reveals divine glory and greatness to his disciples. This was necessary for the holy apostles to strengthen their spirit, because soon Christ was to die for the sins of mankind.
The Orthodox Church proclaims that in the Lord Jesus Christ there were two natures - divine and human. At Tabor, Christ transforms human nature (nature), makes it grace-filled and sanctifies. The meaning of this holiday is that after the coming of Christ into the world, absolutely every person can achieve holiness.
After the Incarnation of Christ, human nature is already capable of accepting divine uncreated grace. An example is just the miraculous Transfiguration of the Lord, which the Christian Church solemnly remembers and celebrates on August 19 in a new style.
