We run, therefore, whenever we make advance; and our wholeness runs with us in our advance (just as a sore is said to run when the wound is in process of a sound and careful treatment), in order that we may be in every respect perfect, without any infirmity of sin whatever result which God not only wishes, but even causes and helps us to accomplish. And this God’s grace does, in co-operation with ourselves, through Jesus Christ our Lord, as well by commandments, sacraments, and examples, as by His Holy Spirit also; through whom there is hiddenly shed abroad in our hearts . . . that love, “which makes intercession for us with groanings which cannot be uttered,” . . . until wholeness and salvation be perfected in us, and God be manifested to us as He will be seen in His eternal truth.

The Council of Trent (16th century):
Now they (adults) are disposed unto the said justice, when, excited and assisted by divine grace, conceiving faith by hearing, they are freely moved towards God, believing those things to be true which God has revealed and promised,-and this especially, that God justifies the impious by His grace, through the redemption that is in Christ Jesus; and when, understanding themselves to be sinners, they, by turning themselves, from the fear of divine justice whereby they are profitably agitated, to consider the mercy of God, are raised unto hope, confiding that God will be propitious to them for Christ's sake; and they begin to love Him as the fountain of all justice; and are therefore moved against sins by a certain hatred and detestation, to wit, by that penitence which must be performed before baptism: lastly, when they purpose to receive baptism, to begin a new life, and to keep the commandments of God. Concerning this disposition it is written; He that cometh to God, must believe that he is, and is a rewarder to them that seek him; and, Be of good faith, son, thy sins are forgiven thee; and, The fear of the Lord driveth out sin; and, Do penance, and be baptized every one of you in the name of Jesus Christ, for the remission of your sins, and you shall receive the gift of the Holy Ghost; and, Going, therefore, teach ye all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost; finally, Prepare your hearts unto the Lord.
This disposition, or preparation, is followed by Justification itself, which is not remission of sins merely, but also the sanctification and renewal of the inward man, through the voluntary reception of the grace, and of the gifts, whereby man of unjust becomes just, and of an enemy a friend, that so he may be an heir according to hope of life everlasting.
