Which of these were Martin Luther's criticisms of the Catholic Church?

One of Martin Luther's major criticisms of the Catholic Church was its practice of selling indulgences, which he believed undermined the true nature of repentance and forgiveness. He argued that salvation should be based on faith alone, rather than on good works or the purchasing of indulgences.

Additionally, Luther criticized the Catholic Church for its belief in the authority of the Pope and the hierarchy of the Church. He argued that religious authority should be derived from the Bible and that all believers should have direct access to the Word of God. Luther believed that the Pope and the Church's hierarchy had become corrupt and were more concerned with acquiring wealth and power than with the spiritual well-being of the faithful.

Luther also condemned the practice of celibacy among Catholic clergy, arguing that it went against natural human desires and often led to sexual misconduct. He believed that clergy members had the right to marry and have families, which would ultimately lead to a more virtuous and committed clergy.

Another criticism of Luther was the excessive wealth and luxurious lifestyles of Church officials. He denounced the accumulation of wealth by the Church, arguing that it should be used to help the poor and needy rather than being spent on opulent buildings and extravagant lifestyles.

Overall, Luther's criticisms of the Catholic Church were centered around the issues of indulgences, papal authority, celibacy, and excessive wealth within the Church.
