Your Question: What is the difference between a disciple and an apostle?

The differences between what we has been considered a disciple and apostle in the Christian tradition is basically that of a student and teacher.

"Disciple" is a general term for any student or follower of a particular teacher. So, Jesus had many disciples, but we most often think of "the Twelve disciples" whom were closest to Jesus during his life.

"Apostle" comes from the Greek word apostolos which means "one sent off or commissioned." An Apostle is one who is sent to represent the one who sent him or her. The Apostle acts and speaks in the sender's place. After Jesus' Resurrection and Ascension to the Father, and the descent of the Holy Spirit upon the disciples in the upper room, the Twelve Disciples are called Apostles--they were given Jesus' Spirit to go out into the world the preach the Word of God as Jesus' representative. They were specifically commissioned and sent by Jesus to make disciples of all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Spirit (Matthew 28:19).

All baptized Christians are disciples of Jesus Christ. We also draw a close connection between our reception of the Sacrament of Confirmation and becoming Apostles for Jesus in the world. Thus, both of these terms apply not only to those living in Jesus' time, but also to us today.
