Paul also continues to describe who the "faithful people" are
 who are to hand on the Revelation of God.
The first category of "faithful people" is episcopos, bishop.
1 Timothy 3:1-2 
This saying is trustworthy: whoever aspires to the office
of bishop (episcopes) desires a noble task. Therefore,
a bishop (episcopon) must be irreproachable, married
only once, temperate, self-controlled, decent, hospitable,
able to teach.
