Can we be saved by faith alone?
No, we cannot be saved by faith alone. This is a heresy begun by Martin Luther in the year 1517.
Luther's idea of faith meant a man's confidence that his sins had been forgiven by God for Christ's sake, but Christ and His apostles always taught that faith implied the acceptance of all God's revelation on His word. Without faith justification is impossible. But other dispositions are required, as faith necessarily leads to action. We must not only believe, but we must hope, repent, and love.
"faith apart from works is dead." (James 2:26)
"We are saved by hope." (Romans 8:24)
"Repent and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins…" (Acts 2:38)
"[I]f I have all faith, so as to remove mountains, but have not love, I am nothing." (I Corinthians 13:2)
