The Catholic Church's control over the sacraments was its most powerful tool in maintaining its authority in medieval Europe. The Church held the power to administer and control important religious sacraments such as baptism, confession, communion, marriage, and last rites. This control allowed the Church to regulate many aspects of people's lives and maintain its influence and control over the spiritual well-being of the population. Additionally, the Church's control over the sacraments also contributed to its ability to consolidate wealth and power.
