Actual Grace is needed for conversions
God will not force His grace upon anyone. He insists that every person accept His ordinary channels of grace: the sacraments, sacramental s, people, circumstances, events, things. When a man does not believe in God’s power to use anything or anybody as His instrument, God gives His grace to other men who do so believe. To disbelieve, and to reject God’s way and time for answered prayer, is to be like the Nazarene s who rejected Christ. (1)
Grace. Strictly, a supernatural (q.v.) gift of God to an intellectual creature, bestowed with a view to eternal life. In 1713, In his bull Unigenitus, Pope Clement XI condemned the Jansenist, (today Feeneyites) proposition that, “no grace is given outside the Church.” (2)
Grace, Actual. Any supernatural (q.v.) and transient aid by which God enlightens the mind or assists the will to produce supernatural acts. It affects the faculties of the grace (q.v.) the faculties of the soul (intellect and will) , whereas habitual grace (q.v.) affects the very substance. Such grace may be given either immediately. (No man cometh to me, except the Father….draw him,” John vi, 44), or mediately, on the occasion of a reading of Scripture or the hearing of a sermon, from joy or a sorrow, a dream, a sunset, or a song. How could anyone be converted without Actual Grace?
We have a clear indication of this in Act’s 10: 44-48 Where the Gentiles received the Gifts of the Holy Ghost before they were Baptized.
44 While Peter was still speaking the Holy Spirit came down on all the listeners.
45 Jewish believers who had accompanied Peter were all astonished that the Grace of the Holy Spirit should be poured out on gentiles too,
46 since they could hear them speaking in tongues and proclaiming the greatness of God. Peter himself then said,
47 ‘Could anyone refuse the water of baptism to these people, now they have received the Holy Spirit just as we have?’
48 He then gave orders for them to be baptised in the name of Jesus Christ. Afterwards they begged him to stay on for some days. Acts 10: 44-48
