Secret disciple?

Joseph of Arimathea is a "secret disciple of jesus" who previously feared recriminations from the Jewish Priests.
- John 19:38

He was simply a previously unknown "follower of jesus"
- Matt 27:57

He was an honored member of the Jewish high court who was "eagerly expecting the arrival of god's kingdom"
- Mark 15:42,43, Luke 23:50

Now, if everybody who was "eagerly expecting the arrival of god's kingdom" was a disciple, then there must be have been millions of 'em running around the place...
