And then there were 11.. I mean 12.. I mean 13?? How many Apostles were there anyway?

Figured we would go a lighter route since it has been a while since I have done so.  How many True Apostles were there.  I assume we will all agree that Judas was not.. but Matthias?  Paul?  My opinion is that Matthias was mans choice and was not a true Apostle, Paul was God's choice.  I will also argue that the Bible is clear that there are only 12....
