Holier Than Thou - Biblical Contradictions

Who was the tenth apostle, Lebbaeus surnamed Thaddaeus or Judas son of James?

Matthew 10:2-4, "These are the names of the twelve apostles: first, Simon (who is called Peter) and his brother Andrew; James son of Zebedee, and his brother John; Philip and Bartholomew; Thomas and Matthew the tax collector; James son of Alphaeus, and Thaddaeus; Simon the Zealot and Judas Iscariot, who betrayed him."

Mark 3:16-19, "These are the twelve he appointed: Simon (to whom he gave the name Peter); James son of Zebedee and his brother John (to them he gave the name Boanerges, which means Sons of Thunder); Andrew, Philip, Bartholomew, Matthew, Thomas, James son of Alphaeus, Thaddaeus, Simon the Zealot and Judas Iscariot, who betrayed him."

Luke 6:13-16, "When morning came, he called his disciples to him and chose twelve of them, whom he also designated apostles: Simon (whom he named Peter), his brother Andrew, James, John, Philip, Bartholomew, Matthew, Thomas, James son of Alphaeus, Simon who was called the Zealot, Judas son of James, and Judas Iscariot, who became a traitor."

Acts 1:13, "When they arrived, they went upstairs to the room where they were staying. Those present were Peter, John, James and Andrew; Philip and Thomas, Bartholomew and Matthew; James son of Alphaeus and Simon the Zealot, and Judas son of James."

The three synoptic gospels (Matthew, Mark, and Luke) list the twelve apostles, however, Luke lists the tenth apostle as Judas son of James, whereas Matthew and Mark consider it to be Thaddaeus. Since Luke wrote the Book of Acts, Judas son of James is listed here as one of the original Twelve.

"Sorrow is better than laughter: for by the sadness of the countenance the heart is made better. The heart of the wise is in the house of mourning; but the heart of fools is in the house of mirth." (Ecclesiastes 7:3-4, KJV)
