It’s true. Corruption within the Church was perhaps the match that lit the candle of the Reformation. The corruption was connected to doctrine and practice.
**Well, first you need to define what type of corruption you are talking about. Too many people just label the Church as ‘corrupt’ all throughout the medieval/renaissance period. When I talk about corruption, I refer to the attitude of being more worldly than spiritual, especially for the clergy. Other people label the wealth of high ranking clergy ‘corrupt’, but that really is just an opinion on how to define ‘corrupt’. **
The Catholic Church at that point laid enormous emphasis on ‘good works’ and the benefits from them. For example, say a few Hail Marys and you get so many merits.
The Church has always laid an enormous emphasis on good works, because they are absolutely necessary for salvation, as it says in the Gospels and the letters of the Apostles. However, to simply generalize the Church as caring about works rather than faith is no more credible than the ‘Catholics try to work their way into heaven’ accusations thrown against the Church by anti-catholics.
Luther, of course, was incensed by Tetzel, a fundraiser for the construction of St. Peter’s in Rome. Tetzel was telling the faithful - to some degree threatening - that giving to the fund would help get their loved ones out of purgatory quicker.
What John Teztel said was in no means representative of official Catholic Church teaching. He liked to exaggerate. However, there are many accusations about what he supposedly said against him that are simply that, accusations, which have no credible sources to back them up.
Luther responded with his 95 theses in which, among other things, he argued that you could not buy your way into or out of anything.
He also argued many heretical opinions which he was ordered to recant by Pope Leo X in his Bull ‘Exsurge Domine’.
This ld him to emphasize faith above everything else, a way of minimizing the part ‘good works’ played in individual salvation. Perhaps he carried this too far, as reform movement often do. Obviously, good works (meaning kind deeds, but not reciting packaged prayers) play a major role among Christians - or should.
He went way too far the moment he held the heretical belief of ‘Sola Fide’. As I said earlier, good works are absolutely necessary for salvation as it says in the Gospels and the letters of the Apostles. Praying for others is a good deed, however you must be contrite and actually mean it.
There were other factors at play. Nationalism. Printing press and the greater availability of the Bible. The luxuries which the Pope enjoyed in Rome. Buying and selling high positions within the church. The rogue behavior of some Popes which brings to mind modern sex scandals among the clergy. Protestantism rebelled against the looseness which characterized so much of the church despite its outward piety. Etc.
**Yes, there were numerous problems the Church faced which took a while to reform. However, just because some Popes were considered moral reprobates does not justify Martin Luther’s heresy and breaking with the One, True Church that was established by Christ. As the saying goes, ‘Don’t leave Peter because of Judas’. **
