<<that we do not earn our salvation, >> We both agree
<<By grace alone>> we owe our entire existence, because God created us, and loves us (his grace) and when the world fell, He also made the plan for our salvation.
1. <Can you lose your salvation> of course, through committing Mortal Sin. You were Catholic, you know what a Mortal Sin is.
2 <What are the grounds of losing your salvation> Again, committing a Mortal Sin, which means you with full knowledge and consent and active will of committing such an act, such as, for example, Pre-Meditated Murder, slander, marital infidelity, etc.
3. <And if your under damnation, what must you do to return to the state of God's grace?>
Confess, repent, make reparation if possible, and commit "the" sin no more.
<You have to DO something, right?>
Well, DUH. It is what I have been trying to tell you all along, isn't it? Faith and "works". "WORKS", not the Mosaic Law kind of works, but "Works" like we're talking about here. Finally, some connection.
<Your salvation is at stake, no? >
I told you this about, 20 responses ago, and now you agree?? Hallelujah.
<So salvation is never truly by Grace now is it?>
You don't think it was by anything other than the Grace of God that Jesus was conceived of Mary, the Virgin Mother of God, (remember Luke 1:28 And the angel being come in,
said unto her: Hail, full of GRACE, the Lord is with thee: blessed art thou among women.)
and that Jesus is the Way, the Truth,and the Life, and the means of our Salvation?
Ultimately EVERYTHING goes back to God's grace.
<Coupled with Faith and Grace we do our part, and He does His part. Grace in cooperation with works.>
ROFL you don't know how Catholic you sound. YES Therefore, Sol Fide is WRONG. THANK YOU FOR PROVING MY ARGUMENT.
