Today we celebrate Christ's transfiguration. The Transfiguration of Christ is the culminating point of His public life, as His Baptism is its starting point, and His Ascension its end. Moreover, this glorious event has been related in detail by St. Matthew (17:1-6), St. Mark (9:1-8), and St. Luke (9:28-36), while St. Peter (2 Peter 1:16-18) and St. John (1:14), two of the privileged witnesses, make allusion to it. About a week after His sojourn in Cæsarea Philippi, Jesus took with him Peter and James and John and led them to a high mountain apart, where He was transfigured before their ravished eyes. St. Matthew and St. Mark express this phenomenon by the word metemorphothe, which the Vulgate renders transfiguratus est. The Synoptics explain the true meaning of the word by adding "his face did shine as the sun: and his garments became white as snow," according to the Vulgate, or "as light," according to the Greek text. This dazzling brightness which emanated from His whole Body was produced by an interior shining of His Divinity. False Judaism had rejected the Messias, and now true Judaism, represented by Moses and Elias, the Law and the Prophets, recognized and adored Him, while for the second time God the Father proclaimed Him His only-begotten and well-loved Son. By this glorious manifestation the Divine Master, who had just foretold His Passion to the Apostles (Matthew 16:21), and who spoke with Moses and Elias of the trials which awaited Him at Jerusalem, strengthened the faith of his three friends and prepared them for the terrible struggle of which they were to be witnesses in Gethsemani, by giving them a foretaste of the glory and heavenly delights to which we attain by suffering.
The twelve apostles chosen by Jesus formed the bedrock of the early Church , and their Catholic identity is deeply rooted in their direct relationship with Christ and the mission He entrusted to them. The Catechism of the Catholic Church highlights this foundational role, stating that Jesus "instituted the Twelve as 'the seeds of the new Israel and the beginning of the sacred hierarchy'" ( CCC 860 ). These men were not simply followers; they were handpicked by Jesus, lived intimately with Him, witnessed His miracles and teachings firsthand, and were specifically commissioned to preach the Gospel to all nations ( Matthew 28:19-20 ). Their unique position as eyewitnesses to the life, death, and resurrection of Christ, and their reception of the Holy Spirit at Pentecost, established them as the authoritative leaders of the nascent Church, a reality echoed in the writings of early Church Fathers like Ignatius of Antioch, who emphasized the apostles' authority as repre...
