I was watching a video on youtube : <http://www.youtube.com/watch?v=nLh8xnf_Qx0> That I didn't have an answer for. He gives the argument that Matthias became the 12th apostle by the casting of Lots. And then he says that Barnabas and Paul were referred to also by the words apostles. So he argues that apostleship continues on into the current age. What is the contest to this?
