2017 marks the 500th anniversary of the Protestant Reformation . And as part of the five-hundredth - anniversary festivity , we need to speak aboutbutter . Yes , the tasty stuff you spread on goner and rapier into a scorched potato . In an queer plait of history , butter may have played an outsize part in stoking an point-blank German monastic name Martin Luther ’s frustration with the Roman Catholic Church . In fact , if not for a butter forbiddance , Protestantism might have had a much slower maturation .

The story begins in Medieval Europe , where " fast days " were a fully grown deal . According to " Butter : a Rich story " by Elaine Khosrova , the custom started with monks abstaining from eating any animal products on Wednesdays , Fridays , Saturdays and all during Lent , the 40 - day period guide up to Easter . Meat and dairy was believed to fire lust , write Khosrova . Eventually the Church extended the fast twenty-four hour period rules to all Christians — no meat , milk , egg , animal fats or butter .

The problem was that theRoman Catholic Churchwas centered in , you judge it , Rome . And people in Southern Europe did n’t eat on a lot of butter back in the fifteenth and sixteenth hundred . Their diet was dominated by Pisces the Fishes and Olea europaea oil , both of which were whole acceptable on fast days . allot to " A History of Food " by Maguelonne Toussaint - Samat , some Southern Europeans believed that buttercausedleprosy and packed their own supply of petroleum if traveling afield .

Martin Luther nailing butter to door

Up north in dairy farm - land land like France and Germany — where Luther lived — cutting butter from the diet was a much bigger deal . After losing essence and cheese , there was middling much nothing leave . And since fast days cross almost half the calendar year , the butter forbiddance was akin to starvation .

Indulging in Butter

For well - link up royalty and other wealthy faithful , the church was known to yield reprieves or " dispensations " on the butter forbidding . Other powerful requester made donation to Rome — alms for chapel construction and money to fund the crusades — in takings for exemption to eat butter .

In some cases , intact neighborhood were granted license to rust butter , but only in interchange for an ongoing unearthly " tax . " A peculiar collection boxwood was placed in French parishes to collect butter money , which may have been used to fund the building of new towboat for ornate cathedral like those inRouenandBorges , lie with to locals as the " Tour de Buerre " or " Butter Tower . "

Meanwhile , the poor blackjack in Luther ’s parish were stuck with the " no butter " rule . Even worse , enterprising exporters from Southern Europe were selling rock oil to the northern countries to use on immobile day . Not only was the oil much more expensive compared to local butter , but it was downhearted lineament .

" In Rome , they make a spoof fasting , while pressure us to eat an oil they themselves would not utilize to grease their slipper , " Luther write in " An heart-to-heart letter to the Christian aristocracy of the German nation,“published in 1520 .

But the speculative offense , according to Luther , was that some clergymen were traveling around Germany selling self-indulgence for the sin of corrode butter on fast days . pampering were official church pardons that had been part of Roman Catholic philosophical system for century , but were only to be hold under the condition ofcontrite confession .

Unfortunately , the craziness system was easily corrupt , and the practice of " selling forgiveness " for all sorts of things in the sixteenth hundred was " very , very widespread , " says Kirsi Stjerna , Professor of Lutheran History and Theology at the Pacific Lutheran Theological Seminary .

" There was an ' thriftiness of grace , ' " explain Stjerna . " Today we purchase life story indemnity and health indemnity to secure our possessions . In the Middle Ages , the only security measures came through church building . These indulgences were the multitude ’s insurance insurance policy , tangible pieces of paper that enunciate , ' Hey , I ’m good . ' "

For Luther , these clergy sell indulgence represented the larger sine of a church building that convinced misfortunate peasants that pardon came at a price . In Luther ’s Bible - centered theological system , forgiveness was free , and man would be redeem or " justified " by faith and free grace alone , not by trace the church service ’s rules .

" They sell us the right to eat solid food forbidden on fast days … but they have stolen that same familiarity from us with their ecclesiastical laws , " wrote Luther . " Eating butter , they say , is a bang-up sin than to lie , blaspheme , or indulge in impurity . "

The Spread of Protestantism

" It seems scarcely a concurrence , " writes butter historian Khosova , " that most of the dairy - rich countries producing and using butter were the same nations that broke aside from the Roman Catholic Church in the sixteenth 100 . "

Professor Stjerna agrees that nutrient - related issue — like whether a sure food was interdict on fast days — played a major office in the frustration that built up with the Catholic Christian church .

" That was one of Luther ’s biggest teachings — nothing about feeding , drinking , kip , marrying or sex is wickedness . Not believing in God is sine , " says Stjerna . " In other words , everything is cool . consume butter is cool . One of the cause why the Reformation was so successful was that Luther radically changed how people thought about what ’s amiss and what ’s permissible . "

On October 31 , 1517 , Luther first published his95 Theses , by some report nailing them to a church building door in his hometown of Wittenberg . The 95 Theses presume to call into interrogative sentence the godlike authority of the pope .

Luther ’s teachings , which spread rapidly thanks to the fresh - fangled printing press , forever altered the course of study of Christian chronicle . Today there are more than 45,000 Protestant appellative around the creation .
