I have asked it before on FE, and if I have asked it here too, please forgive me. But I can't reach a conclusion:
For every salutary act internal supernatural grace of God (gratia elevans) is absolutely necessary. (De fide.)
Actual Grace is not necessary for the performance of a morally good action. (Sent. certa.)
And what CM pointed out recently:
"Pope Pius St. V, Ex Omnibus 27: “Free will, without the help of God's grace, has power only for sin.” - CONDEMNED.
The only conclusion I reached is that we can do good without grace, but it will have no effect on our salvation. Also maybe we can avoid some sins (not ofcoarse all sins and not for a considerable amount of time) but still without any effect on our salvation.
Is it right?
