👉 Jesuits are a religious movement that emerged in the 16th century and is often associated with Switzerland. They were a group of Catholic priests who believed in the doctrine of transubstantiation, which means that the bread and wine they ate during their mass were actually made from the body and blood of Jesus Christ. The movement was founded by Martin Luther, an early Protestant theologian and reformer, and it spread across Europe, inspiring many other religious movements in the centuries to come.
