Read thesis 81 and 82 and explain thesis 82 in luther's ninety-five thesis

81) This unbridled preaching of indulgences makes it difficult even for learned men to rescue the reverence which is due the pope from slander or from the shrewd questions of the laity.    82) Such as: ``Why does not the pope empty purgatory for the sake of holy love and the dire need of the souls that are there if he redeems an infinite number of souls for the sake of miserable money with which to build a church?'' The former reason would be most just; the latter is most trivial.

Explanation: Martin Luther is making the point that grace is a much better reason for saving souls from purgatory than paying money, and that to say otherwise goes against the core tenants of Christianity, which views money as dangerous and corrupting, and grace and mercy as the virtues that everyone should strive for and that define Christ.
