Discourse on the Holy Transfiguration of Our Lord God and Savior Jesus Christ of Saint Gregory Palamas, Archbishop of Thessalonica

For an explanation of the present Feast and understanding of its truth, it is necessary for us to turn to the very start of today's reading from the Gospel: "Now after six days Jesus took Peter, James and John his brother, and led them up onto a high mountain by themselves" (Mt.17:1).

The Holy Apostle Peter, the son of Jonah and brother of Andrew the First-Called, of the tribe of Simeon and the town of Bethsaida, he was a fisherman and was at first called Simon, but the Lord was pleased to call him Cephas, or Peter (Jn 1:42). He was the first of the disciples to give clear expression to his faith in the Lord Jesus, saying: "Thou art the Christ, the Son of the living God" (Mt. 16:16). His love for the Lord was very strong, and his faith in Him went from strength to strength. When the Lord was put on trial, Peter denied Him three times, but it needed only one look into the face of the Lord, and Peter's soul was filled with shame and repentance. After the descent of the Holy Spirit, Peter became a fearless and powerful preacher of the Gospel. After his first sermon in Jerusalem, about 3,000 souls were converted to the Faith. 

The Holy Prophet Elijah is one of the greatest of the prophets and the first dedicated to virginity in the Old Testament. He was born in Tishba of Gilead into the Levite tribe 900 years before the Incarnation of the Word of God. 

St Epiphanius of Cyprus gives the following account about the birth of the Prophet Elijah: "When Elijah was born, his father Sobach saw in a vision angels of God around him. They swaddled him with fire and fed him with flames." The name Elijah (the Lord's strength) given to the infant defined his whole life. From the years of his youth he dedicated himself to the One God, settled in the wilderness and spent his whole life in strict fasting, meditation and prayer. Called to prophetic service, which put him in conflict with the Israelite king Ahab, the prophet became a fiery zealot of true faith and piety.

The Feast of Holy Pentecost is celebrated each year on the fiftieth day after the Great and Holy Feast of Pascha (Easter) and ten days after the Feast of the Ascension of Christ. The Feast is always celebrated on a Sunday. The Feast commemorates the descent of the Holy Spirit upon the Apostles on the day of Pentecost, a feast of the Jewish tradition. It also celebrates the establishment of the Church through the preaching of the Apostles and the baptism of the thousands who on that day believed in the Gospel message of salvation through Jesus Christ. The Feast is also seen as the culmination of the revelation of the Holy Trinity.
