I want to know the answer to the following question:
Which writing detailed Jesus' appearance before ascension?
All the background I'm provided with is that "According to the First Epistle to the Corinthians (1 Cor. 15:4), Jesus was raised from the dead ("on the third day" counting the day of crucifixion as the first) and according to the canonical Gospels, appeared to his disciples on different occasions before ascending to heaven.". Is that enough to answer the question?
