The Council of Trent meeting in Santa Maria Maggiore church, Trento (Trent). (Artist unknown; painted late 17th century.)

At the Seventh Session of the Council of Trent, the Roman Catholic Church defines its theology of the sacraments. Arguing that seven sacraments are necessary for salvation; Baptism, Confirmation, the Eucharist, Penance, Extreme Unction, Orders, and Matrimony; the council rejected the teaching of most Protestants that only two were required: Baptism and the Lord’s Supper.
