From Christianity Today – Today in Christian History
March 3, 1547: 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, Holy Orders, and Matrimony—the council rejected the teaching of most Protestants that only two were required: Baptism and the Lord’s Supper.
What Christianity Today wrote is true, but not quite true enough. The statement as posted is misleading. It could be read to suggest that the Church teaches that every individual must receive every one of the seven sacrament because they are “necessary for salvation.”
