Question 1

What does Acts 1:21 mean?

Accepted Answer

Acts 1:21 explains that the group of apostles is looking for someone who has been with them the whole time Jesus was with them, from the beginning of his ministry. The verse sets up the qualifications for choosing a new apostle to replace Judas. Peter is speaking to the other believers after Jesus’ ascension, as they gather in Jerusalem. He is explaining that the person chosen to take Judas’s place must have been a consistent companion of Jesus and the apostles throughout Jesus’ public ministry, not just a recent follower. This requirement shows the importance of firsthand experience with Jesus’ life and teachings for those who would be witnesses to his resurrection.

Question 2

The Greek behind Acts 1:21

Accepted Answer

ἐσυνῆλθεν (synēlthen, from G4905): This word, translated as "companied," means to come together or travel with. It emphasizes that the candidate must have closely accompanied the group, not just been a distant observer. εἰσῆλθεν (eisēlthen, from G1525) and ἐξῆλθεν (exēlthen, from G1831): These words, "went in and out," are a Greek way of describing daily life and activity. They show that Jesus was regularly present and active among the group, and the new apostle needed to have witnessed this firsthand. κύριος (kyrios, from G2962): Translated as "Lord," this word highlights the respect and authority attributed to Jesus by his followers, underlining the seriousness of the role being filled.

Question 3

Why Acts 1:21 matters

Accepted Answer

Acts 1:21 clarifies that apostleship required direct, ongoing experience with Jesus, not just belief in him or later association with the group. The verse helps explain why only certain people could be considered to replace Judas, setting a historical foundation for apostolic authority. This requirement connects to the larger theme in Acts of eyewitness testimony being central to the early Christian message, especially regarding Jesus’ resurrection.
