Hocus Pocus - “body of Christ”
One of the main tenants of Luther’s Protestant Reformation was the discarding of the belief in transubstantiation (that the communion bread literally becomes the body of Christ). There was a famous magician in protestant King James I’s court who would say “hocus pocus” before his tricks, mocking the words Catholics priests spoke before giving communion - “hoc est corpus meum” (This is my body). This intonation before doing a magic trick carries on today.
