On the Celebration of Easter

De sollemnitate paschali

Written about 325 to 335, probably in Caesarea Maritima (now Caesarea, Israel). The date is the usual view of scholars; some doubt it.

A fragment that explains the Jewish Passover as a picture of Christ and defends the Easter date fixed at Nicaea.
