In the New Testament, all the focus is on the reality of the glory of Christ, not the shadow and copy of religious objects and forms. It is stunning how indifferent the New Testament is to such things: there is no authorization in the New Testament for worship buildings, or worship dress, or worship times, or worship music, or worship liturgy or worship size or thirty-five-minute sermons, or Advent poems or choirs or instruments or candles. . . .
Almost every worship tradition we have is culturally shaped rather than Biblically commanded.
—John Piper, sermon: “Our High Priest is The Son of God Perfect Forever”
