Problem: Crucifixion of Jesus:

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. 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. However, most biblical scholars agree that St. Luke also wrote the Acts of the Apostles as a follow-up volume to his Gospel account, and the two works must be considered as a whole.

Who wrote both accounts of the Crucifixion and ascension?
---
A: St. Luke
