The statement that best explains the Catholic Church’s response to the Protestant Reformation based on the summary of the Tridentine Creed is:
The Church reaffirmed core Catholic teachings such as the Eucharist and the supremacy of the Church in interpreting the Bible.
This response reflects the essence of the Tridentine Creed, which emphasizes fundamental Catholic doctrines and the authority of the Church, contrasting with the Protestant emphasis on individual interpretation of scripture and the validity of certain sacraments.
