Technically; you are right. The word KEEP or any of it's permutations have escaped your fingers.
However; you DID state the following @#154:
Where they (works) are absent so too is Salvation.
Therefore, to KEEP your salvation; works are required.
I have neither said or implied that. I do not know how I can be any more clear. To repeat; Salvation is the efficient cause of corporeal and spiritual works of mercy. I apologize if Catholic teaching does not comport with the fabrications about it you may have been taught.
Peace be with you
