Luke 24 v 33; and they rose up the same hour, and returned to Jerusalem and found the eleven gathered together and them that were with them
1. Which eleven?
2. Did they include themselves in the numbers they find?
Even if they do, the disciples there (of the elected 12 of Jesus) could never be more than 10 altogether because on this visit of Jesus to that upper room, Judas and Thomas were definitely not present.
Also Paul said that after the days, Jesus was seen of Cephas (Simon Peter) then to the twelve.
3. Which twelve?
The word ‘then’ excludes Peter. Even if you add him, you will never get the twelve because the traitor Judas had committed suicide before the alleged resurrection!
