2:3 and you have perseverance and have endured for My name's sake, and have not grown weary.

This is a continuation from the previous verse:

4) you have PERSEVERANCE and

5) have ENDURED for my NAME's sake and

What did the church endure for Christ's sake? Acts 5:37-42 describes the beatings and reprimands to be silent.

6) have not grown weary.

The church had not grown weary of holding forth the word in Christ's name NOT in the names of "transient apostles".
