I think it's clear enough that displays of the miraculous power of God are required for proof of apostleship (2 Cor 12:12*). To try to water down that verse so that "signs" just means "great works" seems irresponsible. If the Bible even hints that an apostle must prove his apostleship with miracles then we should err on the side of caution.

Apostles should have to prove themselves. We shouldn't have to give them the benefit of the doubt. Neither should we have to go around worrying if we missed an apostle. Apostleship should be clear, and the Bible says that clarity comes by seeing miracles worked.

Fool me once, shame on you. Fool me twice, shame on me.

*"The signs, indeed, of the apostle were wrought among you in all patience, in signs, and wonders, and mighty deeds." Young's Literal Translation
