Introduction
The Solemnity of the Ascension of Jesus Christ, also called Ascension Day, Ascension Thursday, or sometimes Holy Thursday, commemorates the Christian belief of the bodily Ascension of Jesus into heaven. It is one of the ecumenical (i.e., shared by multiple denominations) feasts of Christian churches, ranking with the feasts of the Passion and Pentecost. Following the account of Acts 1:3 that the risen Jesus appeared for 40 days prior to his Ascension, Ascension Day is traditionally celebrated on a Thursday, the fortieth day of Easter; although some Christian denominations have moved the observance to the following Sunday. The day of observance varies by ecclesiastical province in many Christian denominations, as with Methodists and Catholics, for example.
History
The observance of this feast is of great antiquity. Eusebius seems to hint at the celebration of it in the 4th century. At the beginning of the 5th century, Augustine of Hippo says that it is of Apostolic origin, and he speaks of it in a way that shows it was the universal observance of the Catholic Church long before his time. Frequent mention of it is made in the writings of John Chrysostom, Gregory of Nyssa, and in the Constitution of the Apostles. The Pilgrimage of Aetheria speaks of the vigil of this feast and of the feast itself, as they were kept in the church built over the grotto in Bethlehem in which Christ is traditionally regarded as having been born. It may be that prior to the 5th century the event narrated in the Gospels was commemorated in conjunction with the feast of Easter or Pentecost. Some[who?] believe that the much-disputed forty-third decree of the Synod of Elvira (c. 300) condemning the practice of observing a feast on the fortieth day after Easter and neglecting to keep Pentecost on the fiftieth day, implies that the proper usage of the time was to commemorate the Ascension along with Pentecost[citation needed]. Representations of the mystery are found in diptychs and frescoes dating as early as the 5th century.[citation needed]
