to make someone a disciple of Jesus, or (in the passive) to be brought in as one.
This verb is built directly from the noun for a disciple, so at its root it means to have to do with being a disciple. In the New Testament it works in two directions that are really one idea seen from two sides. Used with a direct object it means to make someone a disciple: to bring a person into the committed, learning relationship of following Jesus. Used in the passive it means to be brought into that relationship, to become a disciple.
The key thing to see is that this is more than teaching. Jesus commissions his followers to make disciples of all nations, and in the very next breath he separates that from teaching, which is only one part of the job. To make a disciple is to attach a person to Jesus himself: it begins with baptism and continues in a lifelong following, not merely passing on information. That is why the older rendering "teach all nations" is now widely set aside; it flattens a rich word into a thin one.
The word is rare, appearing only four times, and three of those are in Matthew, who cares more about disciples than any other Gospel writer. It carries a striking note that has no real parallel in the discipleship of the ancient philosophers or the later rabbis: a disciple of Jesus is sent out to make more disciples. The relationship is meant to reproduce itself.
Nuances
Whether the opening participle in Matthew 28:19 should be rendered as a soft "as you go" or as an imperatival "go" that shares the command force of "make disciples."
- majorityIt carries imperatival force: "Go and make disciples." The tense and word order fit the pattern grammarians label attendant circumstance, so the going is part of the command.; Daniel B.
