So, understanding it from this perspective, is it possible to be saved by faith alone? Absolutely not. This is because by saying you are saved by faith alone, you are really saved by believing alone. No one, protestant or catholic, should say we are saved by simply believing and nothing else. That is akin to saying "I believe Christ died for my sins completely. Pass me the bong please!" Obviously, we cannot be saved by belief alone. Remember, even the demons in hell believe. Are they saved?
Often, people will combat this by saying, if you have faith, you wont want to do these things. If you say this, you are using the wrong definition of the word faith. Again, faith simply means a belief in something not yet seen. When you say "if you have faith, you wont want to do those things." you are really saying, "if you believe in that which cannot be seen, you wont want to do those things." Obviously, this cannot be true because as mentioned, I can believe in something, but ignore it.
What then do people mean when they say "if you have faith, you wont want to do these things" They are really saying, if you have a faith that saves, you won't want to do these things. This changes the purpose of faith from simply a belief, to a belief with a qualifier. What is a faith that saves? It means you belief in that which cannot be proven, and you also act on that belief. You are not forced to act on that belief, you choose to because you believe. THis belief is a gift from god, so to, the acting on that belief is meant as a gift for god. You should never do anything for yourself, but for the glory of god lest you boast. If a protestant comes up to a catholic and says we are saved by a saving faith, to a catholic, you are really saying, you are saved by a faith that has works because they are one in the same.
