To share the Gospel and how one acquires salvation one has to be in agreement. Christianity and Roman Catholicism are not in agreement on this.
See how offensive that sounds? See how unnecessarily offensive your posts sound to us? Where in the Bible are you authorized to insult people to spread your "Gospel"? Do you realize how much damage you do to your own position when you say stuff like that?
Scripture says to give a reason for the hope that lies within you, but to do so with "gentleness" and "reverence". Perhaps you should consider obeying that injunctive.
Catholics fundamentally understand salvation as unmerited adoption into God's family, a right which was purchased for us, because obviously nobody could purchase that sort of thing for themselves. That's the truth, in contrast to your caricature.
Many Protestants seem to understand salvation as "penal substitution," which amounts to the acquittal of a criminal based on someone else having "done the time". (Because I do not go around caricaturing someone else's beliefs, I welcome corrections from the Protestants in the audience.)
The penal substitution view is not false, but it is incomplete. If you commit a crime and the President pardons you, you don't get to move into the White House with him, he doesn't include you in his will, and he doesn't start to call you his "son" or "daughter".
God does all of those things, which is why salvation is much more than just a pardon.
I think we agree that salvation is by the grace of God. Some other disagreements, but not to many when you clear away the misunderstandings due to definition of terms.
We can, hopefully, agree that all are seeking truth.
thanks for your reply.
