Catholicism and Salvation

That they who sin had been cut off from God, may be disposed through His quickening and helping grace to convert themselves to their own justification by freely assenting to and cooperating with that grace, so that, while God touches the heart of man through the illumination of the Holy Ghost, man himself neither does absolutely nothing while receiving that inspiration, since he can also reject it, nor yet is he able by his own free will and without the face of God to move himself to justice in his sight.

--Council of Trent, “Decree Concerning Justice,” Sixth Session, 13 January 1547.
