Indulgences
Hus opposed the sale of indulgences. Indulgences were documents of personal
forgiveness from the Pope which were sold for sometimes exorbitant prices
to raise funds for Crusades. he also called for preaching of the bible in all languages and also the giving of full communion to church members. In addition, he also called for higher morality among priests.
The retail industry helps producers sell their goods to a national market.
Said the bible biggest religious authority not the pope.Luther taught that salvation and, subsequently, eternal life are not earned by good deeds but are received only as the free gift of God's grace through the believer's faith in Jesus Christ as redeemer from sin.
These are two of his main points. Their are more though.
