Paschal Triduum
The foundation of canon law is found in its earliest texts and their interpretation in the church fathers' writings. Christianity began as a Jewish sect in the mid-1st century arising out of the life and teachings of Jesus of Nazareth. The life of Jesus is recounted in the New Testament of the Bible, one of the bedrock texts of Western Civilization and inspiration for countless works of Western art. Jesus' birth is commemorated in the festival of Christmas, his death during the Paschal Triduum, and his resurrection during Easter. Christmas and Easter remain holidays in many Western nations.
