Luther was strongly opposed to the sale of “indulgences”. Members of the Catholic Church were expected to pay the church for penance that covered certain types of sins. The pressure on the part of the believers to subscribe to such payments was the belief that unconfessed sins increased the time for one’s stay in purgatory.
Luther became increasingly angry about the clergy selling 'indulgences' - promised remission from punishments for sin, either for someone still living or for one who had died and was believed to be in purgatory. On 31 October 1517, he published his '95 Theses', attacking papal abuses and the sale of indulgences
The Zealots were radical groups of Jewish patriots, who had been active in Judea and Galilee since the beginning of the 1st Century.
Today, the name "zealot" refers to fervent supporters of some doctrine, religious or political group, who fanatically work for the cause to which they are loyal.
Jewish zealots fought against Roman rule by organizing guerrilla detachments and inciting uprisings in cities. The most radical of them also organized the killings, which targeted not only Roman officials but also their allies among Jews.
The various groups of zealots often clashed with each other and accounted for cruel methods in the struggle for domination. When they conquered the region, they used cruel terror not only against Roman allies, but also against the wicked and those who condemned the armed rebellion.
