The word “disciple” comes from the Greek word mathetes (pronounced math-ay-tays).
This word was used in pre-christian literature to describe a ‘pupil’ or ‘apprentice’ who had committed himself to attaining understanding or expertise in a certain field of study. Three things were assumed in ancient discipleship:
– A specific field of knowledge or skill
– A master or expert in that field
– A pupil who was dedicated to learn
Occurrences of the word ‘disciple’ in the New Testament are perfectly consistent with its ancient and secular usage.
At the beginning of his ministry, Jesus was declared by God to be the ‘master’ or ‘expert’ in all matters pertaining to the Kingdom of Heaven, and all men were invited to leave their former callings and occupations to learn from him.
Once they did, these ‘disciples’ were to follow him wherever he went, listen to whatever he said, and become more like him by understanding and obeying his teachings.
While disciples did spend much time with their master (sometime even living together), Jesus was careful to maintain the strict master/disciple relationship structure which had been established in antiquity. He said:
“A disciple is not above his teacher, nor a servant above his master. It is enough for a disciple that he be like his teacher, and a servant like his master.” (Matthew 10:24-25)
Here, the master/discipleship relationship and reward is clearly explained: If a disciple honors and obeys his master faithfully, he will someday become like his master.
In the secular context, a disciple would then presumably ‘graduate’ and become a master himself (eventually taking on pupils of his own).
However, and according to the New Testament, the disciples of Jesus never become masters themselves. It is always enough for them to have become more like their Master.
