Circumcision of Jesus was for many centuries combined on January 1 with the Feast of the Holy Name of Jesus, before the two were separated, and now that the Feast of the Circumcision has disappeared as such from the official Catholic calendar, the other feast may be regarded as celebrating this too. At various points in history, relics purporting to be the holy prepuce, the foreskin of Christ, have surfaced and various miraculous powers have been ascribed to it. A number of churches in Europe have claimed to possess Jesus' foreskin, sometimes at the same time. The best known was in the Lateran
Feast of the Ascension 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 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. Representations of the mystery are found in diptychs
