Your point is ludicrous. There were 12 original Apostles - after Judas betrayed Christ - then Matthew was selected to replace him. However, Paul, was also an Apostle, but not one of the original 12. The foundations of the New Jerusalem are in honor of the original 12 - all who died a martyr’s death - except for John. And, the Apostles planted churches - duh! We don’t find the word missionary in the Bible, but, their role is to evangelize and plant churches. Exactly, what the Apostles in the Bible did.
Dig deeper.
Peter replaced Judas so that the Office of Apostle was filled.
All believers are “sent”, but only 12 Apostles hold the Office and will sit on the Throne and are called the foundation of the Church.
