Final answer:
During the Reformation, Protestants rejected practices such as transubstantiation, pilgrimages to holy sites, veneration of saints and relics, and clerical celibacy.
Step-by-step explanation:
The practices of Roman Catholicism that were rejected by Protestants during the Reformation include:
- Transubstantiation: This refers to the belief that the bread and wine used in the Eucharist actually become the body and blood of Jesus Christ. Protestants rejected this concept and instead believed in the symbolic nature of the bread and wine.
- Pilgrimages to holy sites: Protestants viewed the practice of traveling to holy sites as unnecessary and believed that one could have a personal relationship with God without the need for such journeys.
- Veneration of saints and relics: Protestants rejected the veneration of saints and relics, considering it to be idolatry and a deviation from the true worship of God.
- Clerical celibacy: Protestants disagreed with the mandatory celibacy of the clergy in the Catholic Church and allowed their clergy to marry.
