Who was Thaddeus?
Thaddeus, also known as Lebbaeus and sometimes identified with Judas son of James (not Iscariot), was one of the twelve apostles of Jesus Christ. His name appears in the apostolic lists of the Synoptic Gospels, particularly in Matthew 10:3 and Mark 3:18, while Luke 6:16 and Acts 1:13 refer to him as “Judas son of James.” This dual naming has led to scholarly discussions, but traditional Christian teaching affirms that these names refer to the same individual.
The name Thaddeus (Greek: Θαδδαῖος, Thaddaios) is likely derived from the Aramaic Taddai, meaning “heart” or “breast,” connoting “courageous” or “wise-hearted.” The alternate name Lebbaeus (Λεββαῖος) may come from the Hebrew lev, meaning “heart,” reinforcing a similar meaning. His identification as Judas son of James (Ἰούδας Ἰακώβου) likely denotes a familial relation, possibly meaning “Judas, son of James” or “brother of James,” depending on interpretation.
Biblical References
- Matthew 10:3 – “Philip and Bartholomew; Thomas and Matthew the tax collector; James son of Alphaeus, and Thaddeus.”
- Mark 3:18 – “Andrew, Philip, Bartholomew, Matthew, Thomas, James son of Alphaeus, Thaddeus, Simon the Zealot.”

- Acts 1:13 – “When they arrived, they went upstairs to the room where they were staying… James son of Alphaeus and Simon the Zealot, and Judas son of James.”
While little is written specifically about Thaddeus’ actions during Jesus‘ earthly ministry, his presence among the Twelve affirms his role as a chosen apostle, entrusted with the mission to preach the gospel, cast out demons, and heal the sick (Matthew 10:1-8).
Possible Appearance in John
Some identify Thaddeus with the “Judas (not Iscariot)” who asked Jesus a question in John 14:22:
“But, Lord, why do you intend to show yourself to us and not to the world?”
If this identification is accurate, it gives us a glimpse of Thaddeus’ contemplative and sincere heart, wanting to understand the ways of Christ’s self-revelation. Jesus’ response focused on love and obedience: “Anyone who loves me will obey my teaching” (John 14:23).
What Happened in the Bible?
Thaddeus, like the other apostles, was called by Jesus to be with Him, to learn from Him, and to be sent out as a witness to the Kingdom of God. Though the Bible provides limited narrative detail about him, his inclusion among the Twelve indicates his foundational role in the early church. After the ascension of Christ and the coming of the Holy Spirit at Pentecost (Acts 2), Thaddeus, along with the other apostles, would have been involved in spreading the gospel and establishing the early church.
Tradition holds that Thaddeus went on to evangelize in regions such as Syria, Mesopotamia, or Armenia, though these accounts are outside the biblical canon and vary in detail.
What It Means for Today’s Christians
Though Thaddeus is a lesser-known apostle, his example reminds believers that prominence is not required for significance in the Kingdom of God. Many Christians serve faithfully in obscurity, and their quiet obedience is no less honored by God. Thaddeus was chosen by Jesus, trained personally by Him, and used in the foundational ministry of the church.
His possible question in John 14:22 also reflects the honest curiosity of a disciple wanting to know more about God’s plan—an encouragement to believers today to bring their questions to Christ with a heart of faith.
How Thaddeus Points to Jesus and the Gospel
Thaddeus’ very presence in the Twelve points to the grace of Jesus in calling ordinary men to follow Him. Jesus equips His followers not based on social status, notoriety, or public acclaim but on the heart surrendered to Him. If indeed he is the same Judas who asked the Lord about His self-revelation, Thaddeus embodies the longing to see more of Jesus—and that longing is answered with the promise of the Spirit and abiding presence (John 14:23).
His life and apostolic mission continued the work of spreading the gospel, testifying to Jesus‘ death, resurrection, and promise of eternal life for those who believe.
Broader Biblical Themes
1. Obscurity and Significance
Thaddeus represents those in Scripture whose work is less visible but no less vital. The Bible affirms that every member of the Body of Christ is necessary (1 Corinthians 12:22–26).
2. Faithful Witness
Though little is recorded about him, Thaddeus remained faithful, a trait seen throughout both the Old and New Testaments in those God uses quietly yet effectively.
3. The Power of Calling
Jesus’ personal calling of the apostles illustrates His sovereign grace in choosing whom He wills (John 15:16). Thaddeus’ life, like the others, testifies to the transforming power of walking with Christ.
4. Seeking Jesus
The question posed in John 14:22, if attributed to Thaddeus, highlights a theme of longing to know Jesus more intimately—an echo of Moses‘ cry, “Show me Your glory” (Exodus 33:18).
