Apostolic Succession
Paul and Barnabas appointed elders for them in each church and, with prayer and fasting, committed them to the Lord, in whom they had put their trust. Acts 14:23
Then Ananias went to the house and entered it. Placing his hands on Saul, he said, “Brother Saul, the Lord—Jesus, who appeared to you on the road as you were coming here—has sent me so that you may see again and be filled with the Holy Spirit.” Immediately, something like scales fell from Saul’s eyes, and he could see again. He got up and was baptized, and after taking some food, he regained his strength. Acts 9:17-19 (Note: it is also possible that this is a reference to Christmaton.)
"Therefore, brethren, select from among you seven men of good reputation, full of the Spirit and of wisdom, whom we may put in charge of this task. “But we will devote ourselves to prayer and to the ministry of the word.” The statement found approval with the whole congregation; and they chose Stephen, a man full of faith and of the Holy Spirit, and Philip, Prochorus, Nicanor, Timon, Parmenas and Nicolas, a proselyte from Antioch. And these they brought before the apostles; and after praying, they laid their hands on them. Acts 6:3-6
I charge you in the presence of God and of Christ Jesus, who is to judge the living and the dead, and by his appearing and his kingdom: preach the word; be ready in season and out of season; reprove, rebuke, and exhort, with complete patience and teaching. For the time is coming when people will not endure sound teaching, but having itching ears they will accumulate for themselves teachers to suit their own passions, and will turn away from listening to the truth and wander off into myths. As for you, always be sober-minded, endure suffering, do the work of an evangelist, fulfill your ministry. For I am already being poured out as a drink offering, and the time of my departure has come. 2 Tim. 4:1-6 (St. Paul hands down his ministry to Timothy)
For this reason I remind you to kindle afresh the gift of God which is in you through the laying on of my hands. 2 Tim. 1:6 (Note: Paul reminds Timothy of the gift he received through laying of hands)
Do not neglect the spiritual gift within you, which was bestowed on you through prophetic utterance with the laying on of hands by the presbytery. 1 Tim. 4:14 (Note: This shows that divine authority is bestowed unto someone using laying on of hands)
In those days Peter stood up among the believers(a group numbering about a hundred and twenty) and said, “Brothers, the Scripture had to be fulfilled which the Holy Spirit spoke long ago through the mouth of David concerning Judas, who served as guide for those who arrested Jesus— he was one of our number and shared in this ministry.” (With the reward he got for his wickedness, Judas bought a field; there he fell headlong, his body burst open and all his intestines spilled out. everyone in Jerusalem heard about this, so they called that field in their language Akeldama, that is, Field of Blood.) “For,” said Peter, “it is written in the book of Psalms, " ‘May his place be deserted; let there be no one to dwell in it,’ and, " ‘May another take his place of leadership.’ Therefore it is necessary to choose one of the men who have been with us the whole time the Lord Jesus went in and out among us, beginning from John’s baptism to the time when Jesus was taken up from us. For one of these must become a witness with us of his resurrection.” So they proposed two men: Joseph called Barsabbas (also known as Justus) and Matthias. Then they prayed, “Lord, you know everyone’s heart. Show us which of these two you have chosen to take over this apostolic ministry, which Judas left to go where he belongs.” Then they cast lots, and the lot fell to Matthias; so he was added to the eleven apostles. Acts 1:15-26
