Following the deep division in the church which had resulted from the Protestant Reformation, there was a widespread desire, which grew stronger and was expressed in a variety of ways, for an ecumenical council. Its aim would be to reject errors against faith, add strength to the official teaching, restore the unity of the church, and reform the standards of the Roman curia and of church discipline.1
FIFTH SESSION, held June 17, 1546.
Decree Concerning Original Sin2
That our Catholic faith, without which it is impossible to please God, may, errors being purged away, continue in its own perfect and spotless integrity, and that the Christian people may not be carried about with every wind of doctrine; whereas that old serpent, the perpetual enemy of mankind, amongst the very many evils with which the Church of God is in these our times troubled, has also stirred up not only new, but even old, dissensions touching original sin, and the remedy thereof; the sacred and holy, œcumenical and general Synod of Trent,—lawfully assembled in the Holy Ghost, the three same legates of the Apostolic See presiding therein,—wishing now to come to the reclaiming of the erring, and the confirming of the wavering,—following the testimonies of the sacred Scriptures, of the holy Fathers, of the most approved councils, and the judgment and consent of the Church itself, ordains, confesses, and declares these things touching the said original sin: Read more about Theology Thursday - The Council of Trent on Original Sin
