A session of the Council of Trent, from an engraving
The Council of Trent was the 19th Ecumenical council of the Roman Catholic Church. Important members of the Catholic Church met in Trento three times between 13 December 1545 and 4 December 1563, in reaction to the Protestant Reformation.
It reinforced Catholic doctrine regarding salvation, the sacraments, and the Biblical canon, answering all Protestant disputes.
