The original twelve disciples/apostles are listed in 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." The Bible also lists the twelve disciples/apostles in Mark 3:16-19 and Luke 6:13-16. A comparison of the three passages shows a couple of minor differences in the names. It seems that Thaddaeus was also known as "Judas, son of James" (Luke 6:16) and Lebbaeus (Matthew 10:3). Simon the Zealot was also known as Simon the Canaanite (Mark 3:18). Judas Iscariot, who betrayed Jesus, was replaced in the twelve apostles by Matthias (see Acts 1:20-26). Some Bible teachers view Matthias as an "invalid" apostle and believe that Paul was God's choice to replace Judas Iscariot as the twelfth apostle.

There was also Judas Iscariot, but after his betrayal of Christ, St. Matthias was chosen to replace him. Apostle means 'one who is sent out'; Jesus sent his Apostles out into the world to spread the Good News. It should be noticed that the Twelve are not the only Apostles.
