Everyone has faith. It's merely a matter of where it's placed.
Salvation is by grace through faith. It's activated when we put our faith in the right person.
Do you think it important that Catholics fully accept your interpretation of Scripture to be saved or is it sufficient that we love the Triune God with all of our hearts, all of our minds and all of our souls?
Neither.
John 1:12-13 But to all who did receive him, who believed in his name, he gave the right to become children of God, who were born, not of blood nor of the will of the flesh nor of the will of man, but of God.
Do you believe that I did not receive Him, do not believe in His name? Do you think there is anything in Catholic doctrine or dogma that would negate that?
Peace be with you.
