I equally agree that Eph.4:11 is not about offices but about gifts as is made clear from the words " he gave gifts to men." My own thinking (and I could be wrong) is that the first three gifts of apostle, prophet and evangelist were unique to the founding of the New Testament church.
It seems to me that these evangelists would have been part of the apostolic team or some kind of assistants to the apostles as is evident from the case of Philip and Steven who were ordained by the apostles in Acts 6 and could therefore also perform miracles just as the apostles did. We don't hear of elders (apart from the apostles themselves) performing miracles in the Scriptures and also in church history.
Therefore it would be safer to say that the gift of evangelist in Eph.4:11 has now ceased. The work of apostles, prophets and evangelists now falls on pastor-teachers. For example, pastors completely rely on the writings of the apostles to shepherd the church. Pastors are also "prophets" in a way because they bring the word of the Lord to the congregation but not as direct revelation as the prophets did. Pastors are also exhorted to do the work of an evangelist like Paul did instruct Timothy.
Just thinking loudly.
