I want to know the answer to the following question:
Who wrote both accounts of the Crucifixion and ascension?
All the background I'm provided with is that "The account given in Acts of the Apostles, which says Jesus remained with the apostles for forty days, appears to differ from the account in the Gospel of Luke, which makes no clear distinction between the events of Easter Sunday and the Ascension.". Is that enough to answer the question?
