The term "disciple" is derived from the a Greek word mathetes, which means a pupil (of a teacher) or an apprentice (to a master craftsman), coming to English by way of the Latin discipulus meaning a learner while the more common English word is student. A disciple is different from an apostle, which instead means a messenger. While a disciple is one who learns from a teacher, an apostle is one sent to deliver those teachings or a message.
In Matthew, "Then the eleven disciples went to Galilee, to the mountain where Jesus had told them to go. When they saw him, they worshiped him; but some doubted. Then Jesus came to them and said, “All authority in heaven and on earth has been given to me. Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age.
What Jesus told His Apostles was to make disciples. But as disciples we are to grow in the Faith, learn more and more from the Bible and spiritual leaders in our Church and then become apostles ourselves. For how could we spread the Good News if we aren't learned in what the Good News is? Find disciples then those disciples grow in the knowledge of the Lord and then become apostles to spread the message....from Master to student then student becomes Apostle to find more disciples.
What are we doing to grow from disciple to Apostle???
