I’m glancing through what was posted; I’m ignoring it on that thread so as not to ignite a flame war... yet.
But... works can add to grace? REALLY?! How on earth does it keep being grace then?
Duplicitous thinking is a hallmark of Catholic apologists on these threads.
Romans 11:6 But if it is by grace, it is no longer on the basis of works; otherwise grace would no longer be grace.
Grace is grace beginning to end.
grace

a : unmerited divine assistance given to humans for their regeneration or sanctification
b : a virtue coming from God
c : a state of sanctification enjoyed through divine assistance
The Catholic definition of grace is different from what it really is. They don't get that you don't have to do anything to get it. God just gives it because........ We didn't/couldn't work to earn it in the first place, and we don't/can't work to keep it or continue to be given it.
