Jesus' appearance after resurrection

[sforces]

I guess my next question is which account is the right one?

There are discrepancies probably because the NT is a bunch of letters/recollections to others. Some of the things in the letters came from the writer's own mind and not everything is necessarily God inspired.

I believe there are three things in the NT letters

1. Recollection of events from the mind (poss with some help from the HS)
2. Revelations given to the apostles directly from God
3. Teachings/examples from what the apostles believed/understood (which came from their minds)

Like the scribe who when he becomes a disciple brings old (understanding) and new. Paul probably would have fit into that description.
