In the Bible it mentions the apostles meeting together in prayer to determine who the lord would have them choose to fill the apostolic vacancy left by Judas.
Acts 1:23 And they appointed two, Joseph called Barsabas, who was surnamed Justus, and Matthias.
24 And they prayed, and said, Thou, Lord, which knowest the hearts of all men, shew whether of these two thou hast chosen,
25 That he may take part of this ministry and apostleship, from which Judas by transgression fell, that he might go to his own place.
26 And they gave forth their lots; and the lot fell upon Matthias;
From this account we see that the lord intended the apostleship to continue however history shows that it did not. How long did the practice of replacing the fallen or deceased apostles continue after this account and why did it stop happening?
