that position ended in 70AD, people seem to overlook the fact that they were "temporary" overseers during the transition period i.e. the "this generation" (40yrs). From Pentecost to Parousia was 40yrs. Who do you think he is talking to in Acts? The "you" isn't anyone today. It is the "you" in the first century he is talking to. Audience relevance and syntax, dorks. The one and only shepherd is Christ and the temporary shepherds ended when the "perfect" came in 70AD at the Parousia of Christ i.e. the end of AGE(s). We are in the eternal age of Messiah that has no last days, no End. The only end in scripture or last days all concerned national ethnic Israel, the son's of Jacob, and the end of the AGE of Moses and the law i.e. the old covenant, the old heaven and earth (Isaiah 51:15-16) the temple and city (plus all the other OC types and shadows).
