The tool that was most powerful for the Catholic Church in maintaining its authority during this time period would be control over the sacraments. The sacraments, such as baptism, confirmation, marriage, and the Eucharist, were seen as essential for salvation in the Catholic faith. By having control over the administration of sacraments, the Church had the power to grant or withhold access to these religious rituals, effectively maintaining its authority over the lives and spirituality of its followers. Additionally, the Church claimed to hold the keys to heaven and the power to forgive sins through the sacrament of confession, further cementing its authority and control over individuals' religious lives.
