Step-by-step explanation:
Ulrich Zwingli's Main Religious Beliefs:
Ulrich Zwingli, a leader of the Reformation in Switzerland, held several theological positions that diverged significantly from Roman Catholic doctrine. Zwingli rejected the Catholic concept of transubstantiation, challenging the belief that Jesus is physically present in the consecrated communion elements. He advocated for the removal of religious imagery from churches, opposed clerical celibacy, and spoke against practices like fasting before religious holidays. Additionally, Zwingli believed that the Bible should be available in vernacular languages, such as German, rather than Latin. His stance on baptism was also radical for the time; he proposed that baptism should be an adult choice rather than an infant ritual. Zwingli's teachings played a pivotal role in shaping Protestant beliefs and establishing reforms that later influenced various Protestant movements.
