How Old Were Jesus’ Disciples?

Sonlife Team Members

In many painted and on-screen depictions of Jesus and his ministry, Jesus’ disciples appear to be older men, or at least older than Jesus himself. Digesting these portrayals can lead us to draw faulty conclusions about the nature of Jesus’ ministry. That’s not a good place to start when it comes to understanding discipleship to Jesus.

Do we know how old Jesus’ disciples were? Not much has been written on this topic from a scholarly perspective, perhaps because there’s not much explicit evidence to go on. We have a few clues from Biblical passages:

Some Biblical clues:

  • Luke 3:23 – Jesus was about 30 when he began his ministry. He probably would not invite disciples who were older than him.
  • John 1:35-40 – Some of Jesus’ disciples were previously disciples of John the Baptist. Therefore, when they transferred their allegiance to Jesus, at John’s request, they may have already had about six months to a year of experience as a disciple.
  • Matthew 4:18-22 – Some of the disciples were old enough to work for the family business, meaning they were at least older than 13 (Peter, Andrew, James, John) when they were invited to learn from him how to fish for people.
  • Matthew 8:14 – We know Peter was married, because he had a mother-in-law, and men in that culture were expected to begin pursuing marriage between the ages of 18-20.
  • Matthew 17:24-27 – We know, from Exodus 38:26 that men over the age of 20 were expected to pay the Temple tax. When the tax collectors queried Peter about Jesus’ payment of this tax, Jesus miraculously provided enough for both Peter and Jesus to pay. This might indicate that the rest of the disciples were not yet of taxable age, thus, in their late teens.

None of these passages provide a “slam dunk” for understanding the ages of the disciples when they began to follow Jesus, but some more recent authors have tried to get us closer:

Otis & Frank Cary, father and son missionaries in Japan, wrote an article called “How Old Were Christ’s Disciples” in the publication The Biblical World in 1917. One of their more creative contributions to the discussion points out that nicknames are often used by the young,

is it too fanciful to suggest that something student-like may be seen in the extra names borne by several of the disciples? In American colleges, some men are better known to their mates by nicknames than they are by their proper designations. … In the universities of the Middle Ages and among the Greeks, we find a similar custom, the new name being sometimes given by the teacher. In the little company of the disciples, we find Cephas, Didymus, Zealot, Boanerges, Thaddaeus, and perhaps other “surnames.” Some of these are known to us by only single incidental references; it is therefore not unlikely that some names were used that are not mentioned. (Carey & Carey 6)

Authors Ann Spangler & Lois Tverberg, in Sitting at the Feet of Rabbi Jesus, round out the possible lower end of the ages of the disciples by applying knowledge of later rabbinical methodology and educational practices to Jesus’ first-century ministry. According to their estimates, the disciples grew up in a culture where early education revolved around knowledge of the Scriptures. They seem to prefer 13 as the bottom end of the scale…

  • 5-6 years old = Memorization of Hebrew Scripture
  • After 10 years old = Learn Oral Torah (Rabbinic traditions handed down)
  • By 13 years old = Conclusion of formal study, begin to learn trade. Some would apply for bet midrash at synagogue
  • Between 18 – 20 = Marriage

(Spangler & Tverberg 24-25)

Laurence Cox, a graduate student at King’s College, London, wrote a paper in 2016 for his thesis titled, “How Old Were Jesus and His Apostles?” One of Cox’s unique contributions to the Biblical evidence is the use of the word “young” (Gk: neos) throughout the Gospels, Acts, and other New Testament writings (Cox 14-15). In comparison to the two previous works listed, Cox prefers a slightly older estimate of the disciples’ ages as “late teens and early 20s.”

Mike McGarry, in a Biblical Theology of Youth Ministry, also prefers the late teens and early 20s as the possible ages for the disciples. He estimates John’s age to be approximately 15 when he began to follow Jesus. He arrives at this number by reasoning that the Apostle John is generally considered the author of the Revelation, which was written during the reign of Domitian in CE 95-96 (McGarry 45). McGarry concludes his argument by saying,

“It is undeniable that Jesus focused His ministry to the next generation and called them to leave their families in order to follow Him. … It is important to acknowledge that even in Jesus’ day, these men were still considered relatively young. The band of disciples represents Jesus’ drive to build up young leaders who will carry the message of the gospel after He ascended (see John 14). Donald MacLeod observes, “God does use the young, and, in fact, many pioneer ventures and efforts that break out of established ministries and churches are spearheaded by the young. The ministry of Jesus was just such a pioneer effort.” (McGarry 47)

With all this in mind, it seems reasonable to assume a span of 15-25 for the ages of the disciples at the time they were called by Jesus to follow Him.

So, why does this matter?

Sonlife began when a college student (our founder, Dann Spader) was told by a professor that most of Jesus’ initial disciples were probably teenagers. Dann thought to himself, “If Jesus’ disciples were teenagers, then he was basically leading a youth group. So maybe I should just study what Jesus did, and do that.”

We continue to believe that young people, and those who work with young people, have a significant contribution to make to today’s church, much as they did in the origin of this Jesus-movement that we are a part of.

And we believe that Jesus, as a truly human disciple-maker, showed us a way to continue to move this movement forward in imitation of and fellowship with him.
