While faith is really important to our salvation, no where did Jesus or the Apostles teach that we are saved by 'Faith Alone'. The only place in the Bible where 'Faith Alone' is mentioned is in the book of James, Cha 2, "So also faith of itself, if it does not have works, is dead. " James Cha 2 makes it clear that faith alone will not save us, "Do you want proof, you ignoramus, that faith without works is useless? Was not Abraham our father justified by works when he offered his son Isaac upon the altar? You see that faith was active along with his works, and faith was completed by the works."
We have faith, hope, and charity/love. You can have all the faith in the world, but without love you are just a clanging symbol.
Actually, saved through faith is Biblical, but saved by 'Faith Alone' is not biblical.
