 Protestant churches that were not participating in the iconoclasm often selected as altarpieces scenes depicting the Last Supper.This helped the worshippers to recall their theology behind the Eucharist, as opposed to Catholic churches, which often chose crucifixion scenes for their altarpieces to remind the worshippers that the sacrifice of Christ and the sacrifice of the Mass were one and the same, via the literal transformation of the Eucharist.The Protestant Reformation also capitalized on the popularity of printmaking in northern Europe.
