The statement that best explains the Catholic Church's response to the Protestant Reformation is:
The Church reaffirmed core Catholic teachings such as the Eucharist and the supremacy of the Church in interpreting the Bible.
This statement reflects the essence of the Tridentine Creed, which emphasized the established doctrines of the Catholic Church in response to Protestant challenges, reinforcing the Church's authority and the importance of sacraments like the Eucharist while maintaining that only the Catholic Church has the authority to interpret Scripture.
