As we live and learn, we might recall that it was on this date in 1545, in response to the Protestant Reformation, that the Council of Trent (Concilium Tridentinum) was convened by the Roman Catholic Church. Its work concluded in 1563; and its results were published in 1564, condemning what the Catholic Church deemed to be the heresies of Protestants.
