Christ never taught the ugly idea that faith alone without collaboration with grace through good works can save a man. Yet that it the foundational lie of your heretical faith.
Luke 7:48 Then Jesus said to her, Your sins are forgiven. 49 The other guests began to say among themselves, Who is this who even forgives sins? 50 Jesus said to the woman, Your faith has saved you; go in peace.
Acts 15:8 God, who knows the heart, showed that he accepted them by giving the Holy Spirit to them, just as he did to us. 9 He did not discriminate between us and them, for he purified their hearts by faith. 10 Now then, why do you try to test God by putting on the necks of Gentiles a yoke that neither we nor our ancestors have been able to bear? 11 No! We believe it is through the grace of our Lord Jesus that we are saved, just as they are.
Rom 4:4Now to the one who works, his wages are not counted as a gift but as his due. 5 And to the one who does not work but believes in him who justifies the ungodly, his faith is counted as righteousness
Rome formally denounced the saving Gospel at Trent.
And just who was it that spoke these words????
Oh, look at that. It was PETER HIMSELF.
Imagine that......
But note that the woman did by her works express her love for Jesus. Jesus in fact, gently rebukes His host in that very passage for not showing enough kindness through good works. In this beautiful episode we have the heart of Catholic soteriology: penance expressed in good works of love for Our Lord and combined with a resolution to sin no more.
We believe it is through the grace of our Lord Jesus that we are saved
Exactly. We are saved by grace alone, as every pope since St. Peter taught.
Rom 4:4
Indeed, works done for compensation do not save. Works of self-denial done for the love of God and the neighbor save. See the Mary Magdalene episode that you yourself quoted.
