JonNC:
One can be justified, and then lose his justification. You, as a Catholic, might say being in a state of mortal sin, or not in a state of Grace.
OK, so here you are saying that one can be “justified” in the Lutheran understanding of the concept, and subsequently lose his justification which is equivalent to the Catholic concept of not being in a state of Grace which, of course, means that if you die in that state you dont go to Heaven. Seems pretty clear, but then in response to my summary here…
Philthy:
It sounds to me that the Lutheran understanding of Salvation involves an initial point of entry into fellowship with God known as being “justified” (aka born again, regenerated, saved, etc)… This entry into fellowship with God (ie justification), however, does not guarantee that we will actually go to Heaven.
…you say this:
which completely contradicts your initial statement that one can lose their justification, and that justification is a requirement for going to Heaven. Im confused again.
Is justification a requirement for going to Heaven? Y or N, please!
Can justification be lost? Y or N, please!
If both of those questions were answered in the affirmative, then this statement remains true: “This entry into fellowship with God (ie justification), however, does not guarantee that we will actually go to Heaven.” and your “Yes, it does.” needs to be changed to “No, it does not”. Correct?
JonNC:
I would reject the language of “no salvation without sanctification”, because it construes that our actions bring merit, when in fact it is Christ’s merit that brings salvation.
But Jon, you have already stated that sanctification is a requirement of going to Heaven and that sanctification requires cooperation on our part. Its a logically consistent statement regarding salvation from the theology you have presented. How can you possibly “reject it”?!

And just for the record, it contains no mention of “merit”; you introduced that on your own! There is no salvation without justification, and there is no salvation devoid of sanctification.
Blessings!
