A lot of people are saying the question isn't clear and I think I see why. It should read more like "Which version of "faith alone" and "Scripture alone" is binding?"
"Whose" is a pronoun so people immediately think you're referring to a person. In Christianity, people don't set the parameters for what our faith consists of or what the Scripture says. God sets the parameters for the specific points He requires us to believe in. Many Christians use that unspoken pretense to filter your question through.
Your question is getting lost in translation because it introduces the possibility that there is more than one version than "faith alone" and "Scripture alone" and there isn't. I was able to notice this within a fraction of a second of looking at your question, but it's taken a lot longer to explain it.
Ephesians 4:4-6
4There is one body and one Spirit, just as you were called to one hope when you were called;
5one Lord, one faith, one baptism;
6one God and Father of all, who is over all and through all and in all.
