The Church's one foundation is Jesus Christ Our Lord.
Seriously, yes the Apostles were chosen by Jesus to lead His Church and to become with Him the foundation.
Certainly you don't feel we are constantly digging up and replacing the original foundation?
The foundation remains the Apostles and Jesus. To believe that there is no more need for Apostles is to believe we can remove the foundation. Rather, the foundation remains the Apostles and their successors.

But if they be true apostles, then their message will be the same as the first. If their message be different, then the foundation is not the same. And your message is certainly far different.
