At dawn, Jesus summoned His disciples to the mountain and selected twelve of them, as the church hymn expresses, as "human beginnings," so they could serve as His closest witnesses to His deeds and teachings, later sharing with the world all they had witnessed and touched (1 John 1:1). He designated them as apostles, messengers empowered to preach the Gospel and affirm their message through miraculous signs, healing the sick and casting out demons. The blessed Theophylact notes, “Twelve disciples are chosen according to the number of the twelve tribes of Israel,” serving as leaders of the future tribes of the new Israel (Rev. 21:12, 14). From that point, the apostles accompanied the Lord in His travels (Lk. 8:1), witnessed His miracles, participated in His dialogues with the multitudes (Mt. 5:1; 23:1), and engaged in discussions with Him (Mt. 13:10; 15:15; 17:10; 18:1; Lk. 8:9; 9:12; 12:41; 17:5; Jn. 9:2). Their close proximity to the Divine Master gradually opened their understanding of the mysteries of the Kingdom of God (Matt. 16:21; Lk. 17:5), and this enlightenment eventually culminated in the full revelation of the Holy Spirit (Jn. 16:12, 13).
In the enumeration of the twelve apostles provided by the evangelists Matthew (10:2-4), Mark (3:16-19), and Luke (6:14-16; Acts 1:13), only Peter, Philip, James the son of Alphaeus, and Judas Iscariot appear in identical positions; the placement of the others is not fixed, suggesting an equality in authority among them, with Peter being the foremost among equals. The evangelists Matthew and Luke organize the names of the apostles in pairs, likely because the Lord sent them out two by two to spread the Gospel (Mk. 6:7). Peter and Andrew, brothers and sons of Jonah, hailed from Bethsaida, a fishing village by Lake Gennesaret (John 1:41, 42, 44). Andrew was initially a follower of John the Baptist, and at his prompting, he came to Jesus, bringing his brother Simon, to whom the Lord assigned the name Cephas (Syrochaldean) or Peter (Greek), meaning "rock" (1:42). Before their calling by the Lord (Matt. 4:19; Mk. 1:16), both brothers were engaged in fishing and resided in Capernaum, where Peter owned a house (Matt. 8:14; Lk. 4:38). It is explicitly noted that Peter was married (1 Cor. 9:5; Lk. 4:38), yet he undoubtedly had to forsake his profession, home, and wife to follow the Lord consistently. Among Jesus' most trusted disciples (Mt. 17:1; 26:37; Mk. 5:37), Peter, as described by St. John Chrysostom, acted as "the mouth," representing all the apostles in speech (Mt. 19:27; Lk. 12:41) and addressing queries collectively (Mt. 16:16; Mk. 8:29). His name frequently appears throughout the Gospel accounts, and following the Lord’s ascension, he became a prominent proclaimer of Christ’s teachings, particularly to the Jewish people (Galatians 2:7). Two epistles in the New Testament bear his name.
The Apostle Andrew, honored by the Church as the First-Called, does not feature as prominently in the Gospel accounts as his brother, though certain phrases suggest he possessed a unique audacity in the presence of the Master (Mk. 13:3; Jn. 6:3; 6:6; 6:8; 12:22). James and John, the sons of Zebedee and Salome (Mt. 4:21; 27:56; Mk. 10:35; 15:40; 16:1), were also fishermen prior to their calling (Matt. 4:21; Mk. 1:19; Lk. 5:10). John was a disciple of the Forerunner before coming to Jesus, likely receiving initial instruction about the Messiah from him (John 1:35). As apostles, the sons of Zebedee were given the title Boanerges, meaning "sons of thunder,” reflecting the fervor and strength of their preaching (Lk. 9:54), and they, along with Peter, formed Jesus’ closest circle of disciples (Mt. 17:1; 26:37; Mk. 5:37). Within this selected trio, John was especially noted for his love for the Lord, referring to himself in his Gospel as "the disciple whom Jesus loved" (13:23; 19:26; 21:7, 20). His devotion was evident, as he remained with Jesus even during His arrest (John 18:15) and received the Blessed Virgin Mother into his home following the Lord’s crucifixion (19:27). He later preached in Ephesus and authored the Gospel, three epistles, and the Book of Revelation within the New Testament.
