The Council of Trent, held between 1545 and 1563, affirmed several doctrines in response to the Protestant Reformation. Among the options you provided, the most relevant teachings affirmed by the Council include:
- The Seven Sacraments - The Council of Trent affirmed the traditional Catholic understanding of the seven sacraments (Baptism, Confirmation, Eucharist, Penance, Anointing of the Sick, Holy Orders, and Matrimony).
The other options, such as justification by faith alone and the authority of the pope being secondary to that of local bishops, were rejected or addressed differently by the Council. The Council emphasized a more nuanced view on justification that involved both faith and works, countering the Protestant belief in justification by faith alone.
