The elder is also a bishop. This order was changed by men after the order had been established by God.   All traveling elders with universal authority must meet the same criteria of qualification as the local elders.  These are also the qualifications for father and elder of the home.

1 Timothy 3:1-13 This is a true saying, If a man desire the office of a bishop [elder or overseer], he desireth a good work.  A bishop then must be blameless, the husband of one wife, vigilant, sober, of good behavior, given to hospitality, apt to teach; Not given to wine, no striker, not greedy of filthy lucre; but patient, not a brawler, not covetous;  One that ruleth well his own house, having his children in subjection with all gravity;  (For if a man know not how to rule his own house, how shall he take care of the church of God?)  Not a novice, lest being lifted up with pride he fall into the condemnation of the devil.  Moreover he must have a good report of them which are without; lest he fall into reproach and the snare of the devil.  Likewise must the deacons be grave, not doubletongued, not given to much wine, not greedy of filthy lucre;  Holding the mystery of the faith in a pure conscience.  And let these also first be proved; then let them use the office of a deacon, being found blameless.  Even so musttheir wives be grave, not slanderers, sober, faithful in all things.  Let the deacons be the husbands of one wife, ruling their children and their own houses well.  For they that have used the office of a deacon well purchase to themselves a good degree, and great boldness in the faith which is in Christ Jesus.

Let God be true and every man a liar.

Apostles are given the responsibility of protecting the entire flock of God from the attack of the enemy, but with so many voices in the world, each one claiming to be the one that should be listened to, how can you know?  You are responsible to be close enough to God so that you can tell the difference between false apostles and real apostles.

God restored the gifts of the Spirit and apostles & prophets to the church since 1948.  Counterfeits and false gifts abound, but the real is still real.
