What did the reformation change?

Answer 1

Assuming you mean the most popular and general use of the word, I would say simply that people began to break away from Catholicism. People began to think that a priest was not necessary as a mediator between themselves and God. People began to question the authority of the Pope. By people I mean some groups, not the whole population of Europe.

Answer 2

Essentially, Christianity changed from being a single religion to many different sects.

Prior to the reformation, Christianity was Catholicism, whether Eastern or Western. Reformation was a time when many groups took exception to one or more theological tenets or moral aspects of the Catholic Church and rejected (rather then reformed, as may have been orginally intended ) the Church. The result was the creation of many Christian sects. Most started out as single issue regional sects, but they have spread, largely because of the discovery of the "New World".

Answer 3

The (Protestant) Reformation accomplished the following:
(1) It revitalized and purified Christianity. It cultivated genune faith. Towards the end of the Middle Ages, the moral decay, abusive practices and the great scandals that rent the medieval Church produced a diffused feeling throughout Europe that the Church needed to be reformed. After Martin Luther, the superstitions of the ignorant and credulous, indulgences, the cult of Mary, the veneration of a pantheon of saints, pilgrimages to weeping statues and bleeding crosses - serious impediments to the cultivation of authentic faith - were done away with in countries were the Refomation took root.

(2) It enabled emergent nation-states to pull away from the influence of Rome and become truly autonomous (cf. England; Germany; Scotland; the Scandinavian countries). By becoming Protestants, the citizens of these nations were no longer torn between allegiance to the Pope and allegiece to the King. By breaking away from the Roman Catholic Church, the kings of these nations ensured the undivided loyalty (and taxes) of their subjects.
(3) The Bible in the vernacular became vailable to the ordinary man so that he can read for himself what it actually says. Through this, many medieval religious superstitions and practices were debunked.
(4) It gave birth to several Protestant denominations
(5) It sparked the Catholic Counter-Reformation
