In the light of UR, what's a New Testament evangelist?

[martincisneros]

Ephesians 4 says that Evangelists are among the ministry gifts that we should expect to operate among us today.  In the light of UR, what's an evangelist?  Is it the same thing as an apologist?  Or would an apologist be one manifestation of an Ephesians 4 "teacher," while an evangelist would be something else entirely??
