Can you Explain the three main abuses that most distressed church reformers?

The three main abuses that distressed church reformers were clerical corruption, moral laxity among clergy, and the sale of indulgences. Clerical corruption involved the exploitation of power by church officials, leading to nepotism and financial misconduct. Moral laxity referred to priests and bishops failing to uphold the spiritual and ethical standards expected of them, which eroded the church's credibility. The sale of indulgences, which offered forgiveness of sins in exchange for money, sparked outrage and was seen as a blatant commercialization of faith.
