I understand now why ya'll aren't allowed to read the texts for yourselves.
Paul is crystal clear in the passage from Ephesians...and elsewhere there is NOTHING we can do to "earn" our salvation.
For by grace you have been saved through faith.
And this is not your own doing
; it is the gift of God,
not a result of works,
so that no one may boast. For we are his workmanship, created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them.
I’m giving 2:1 odds that s/he’ll completely ignore what St. Paul wrote, and 3:1 odds that s/he’ll claim that Paul only meant Jewish circumcision laws or something equally silly.
It is Catholic teaching that grace is not a result of works, this is why it is in the Letter to the Ephesians.
