The Church teaches clearly that salvation is from Christ's sacrifice alone (CCC 169).If anyone tells you differently, they are incorrect, utterly.
Apparently, Most RC's are thus confused. I thought Rome provided certainty and unity.
canon 32
"If anyone says that the good works of the one justified are in such manner the gifts of God that they are not also the good merits of him justified; or that the one justified by the good works that he performs by the grace of God and the merit of Jesus Christ, whose living member he is, does not truly merit an increase of grace, eternal life, and in case he dies in grace, the attainment of eternal life itself and also an increase of glory, let him be anathema."
01 02 03 04 05 What spirits are of God, and what are not. We must love one another, because God has loved us. [1] Dearly beloved, believe not every spirit, but try the spirits if they be of God: because many false prophets are gone out into the world. [2] By this is the spirit of God known. Every spirit which confesseth that Jesus Christ is come in the flesh, is of God: [3] And every spirit that dissolveth Jesus, is not of God: and this is Antichrist, of whom you have heard that he cometh, and he is now already in the world. [4] You are of God, little children, and have overcome him. Because greater is he that is in you, than he that is in the world. [5] They are of the world: therefore of the world they speak, and the world heareth them.Or take Hebrews 12:14
[6] We are of God. He that knoweth God, heareth us. He that is not of God, heareth us not. By this we know the spirit of truth, and the spirit of error. [7] Dearly beloved, let us love one another, for charity is of God. And every one that loveth, is born of God, and knoweth God. [8] He that loveth not, knoweth not God: for God is charity. [9] By this hath the charity of God appeared towards us, because God hath sent his only begotten Son into the world, that we may live by him. [10] In this is charity: not as though we had loved God, but because he hath first loved us, and sent his Son to be a propitiation for our sins.
[11] Now all chastisement for the present indeed seemeth not to bring with it joy, but sorrow: but afterwards it will yield, to them that are exercised by it, the most peaceable fruit of justice. [12] Wherefore lift up the hands which hang down, and the feeble knees, [13] And make straight steps with your feet: that no one, halting, may go out of the way; but rather be healed. [14] Follow peace with all men, and holiness: without which no man shall see God. [15] Looking diligently, lest any man be wanting to the grace of God; lest any root of bitterness springing up do hinder, and by it many be defiled.Why does he say this? Because God is holy and, if were going to live with God forever, we too must be holy. So our entire life should be a pursuit of the holiness that Christ gained for us by his death on the cross. God desires to put this holiness within us, or as Hebrews 12:10 says, "that we may share his holiness." That is the ultimate rationale behind the Catholic view of salvation: to share in the holiness of God.
