Acts 1 is the first chapter of the Acts of the Apostles in the New Testament of the Christian Bible. The book containing this chapter is anonymous but early Christian tradition affirmed that Luke composed this book as well as the Gospel of Luke. This chapter functions as a transition from the "former account" (that is, Gospel of Luke) with a narrative prelude (verses 1–5), repeated record of the ascension of Jesus Christ with more detail (verses 6–11) and the meeting of Jesus' followers (verses 12-26), until before Pentecost. The original text was written in Koine Greek and is divided into 26 verses. Some early manuscripts containing the text of this chapter are: Codex Vaticanus (AD 325–350) Codex Sinaiticus (330–360) Codex Bezae (~400) Codex Alexandrinus (400–440) Codex Ephraemi Rescriptus (~450; extant verses 3–26) Papyrus 56 (5th/6th century) Codex Laudianus (~550) Psalm ; Psalm 109:8 Acts 1:1-3: Luke 1:1-4 This chapter mentions the following places: Bethany Jerusalem Judea Mount of Olives Samaria The beginning of the book follows a conventional opening statement containing the name of the addressee, Theophilus, and a brief reminder of the content of the "former account" (Gospel of Luke) by the same author. ^1The former account I made, O Theophilus, of all that Jesus began both to do and teach, ^2until the day in which He was taken up, after He through the Holy Spirit had given commandments to the apostles whom He had chosen, ^3to whom He also presented Himself alive after His suffering by many infallible proofs, being seen by them during forty days and speaking of the things pertaining to the kingdom of God. "Former account" (from Greek: , , lit. "first book"): refers to Gospel of Luke. "Theophilus" (written in Greek in vocative word form): the intended reader of this book, as well as the previous one (Luke 1:3), might be a "patron" who is already informed about "things which have been fulfilled among us", but still needs "assurance" to "know the certainty of those things" (Luke 1:1-4).
