Θαδδαῖος
Thaddaeus
Definition
Thaddaeus is the name of one of the twelve apostles of Jesus Christ. In the Synoptic Gospels, he is listed among the Twelve, specifically in Matthew 10:3 and Mark 3:18. In some ancient manuscripts of the Gospel of Matthew, the name 'Lebbaeus' appears alongside or instead of Thaddaeus, which may indicate a dual name or a scribal variation. The Gospel of John refers to an apostle named 'Judas (not Iscariot)' (John 14:22), who is traditionally identified with Thaddaeus, suggesting he may have been known by multiple names.
Biblical Usage
The name Thaddaeus is used exclusively in the lists of the twelve apostles in the Synoptic Gospels. It appears in Matthew 10:3 and Mark 3:18. In both instances, the name is simply listed without any accompanying narrative or dialogue, indicating its primary function is to identify a member of the apostolic group. There is no distinct pattern of usage beyond this formal identification in the apostolic catalogs.
Etymology
The name Θαδδαῖος (Thaddaios) is of Greek origin, but its precise etymology is uncertain. It is possibly derived from an Aramaic or Hebrew root. Some scholars suggest a connection to the Aramaic word for 'breast' (תדא, taddā'), implying 'large-hearted' or 'courageous,' though this is speculative. The variation with 'Lebbaeus' (possibly from a Hebrew root for 'heart') in some textual traditions may support a meaning related to heart or courage.
Semantic Range
Thaddaeus, while a minor figure in the biblical narrative, represents the fulfillment of Jesus's call to a diverse group of twelve apostles, symbolizing the foundation of the New Testament church (Ephesians 2:20). His potential identification with 'Judas (not Iscariot)' in John 14:22 links him to a moment where he asks Jesus a profound question about revelation to the world, highlighting the apostles' role in seeking understanding and bearing witness. Understanding that he may have had multiple names enriches the picture of the apostolic band and the cultural context of naming.
In the first-century Jewish and Greco-Roman world, individuals often bore multiple names (e.g., a Hebrew/Aramaic name and a Greek name) or nicknames that described character traits. The potential dual identity of Thaddaeus/Lebbaeus/Judas reflects this common practice. His obscurity in the Gospels, compared to figures like Peter or John, is typical for many of the Twelve, reminding modern readers that significance in God's kingdom is not always measured by narrative prominence.
Lebbaeus (lebbaios, G3002) — A name appearing in some manuscripts of Matthew 10:3 in association with Thaddaeus, possibly a variant or descriptive nickname. Judas (Ioudas, G2455) — Specifically 'Judas not Iscariot' (John 14:22), traditionally identified as the same apostle as Thaddaeus.
