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 statement reflects the Catholic Church's commitment to its established doctrines and the belief that it alone holds the authority to interpret scripture, directly countering the Protestant emphasis on individual interpretation of the Bible. The emphasis on the sacraments, including the Eucharist, and the role of the Pope also aligns with the reaffirmation of traditional Catholic beliefs during and after the Council of Trent.
