Did Jesus Have Siblings?

[Michie]

There are a number of places in the New Testament (see Mk 3:31-34; 6:3; Mt 12:46; 13:55; Lk 8:19-20; Jn 2:12; 7:3-10; Acts 1:14; and 1 Cor 9:5) where Jesus’ kinsfolk are mentioned using terms such as “brother” (adelphos), “sister” (adelphe) or “brethren” (adelphoi). But “brother” has a wider meaning both in the Scriptures and at the time they were written. It is not restricted to our literal meaning of a full brother or half-brother in the sense of sibling.

Even in the Old Testament “brother” had a wide range of meaning. In the Book of Genesis, for example, Lot is called Abraham’s brother (see 14:14), but his father was Haran — Abraham’s brother (Gn 11:26-28). So, Lot was actually a nephew of Abraham.

The term “brother” could also refer widely to friends or mere political allies (see 2 Sm 1:26; Am 1:9). Thus, in family relationships, “brother” could refer to any male relative from whom you are not descended. We use words like kinsmen and cousins today, but the ancient Jews did not.

In fact, neither Hebrew nor Aramaic had a word meaning “cousin.” They used terms such as “brother,” “sister” or, more rarely, “kin” or “kinsfolk” (syngenis) — sometimes translated as “relative” in English.
