Popes, creeds, councils and tradition have no authority when they contradict the Holy Scriptures. Mystical impressions, emotions, and sensations coming from the heart of man are never authoritative. The Bible is complete and the canon is closed. No further revelation is given. Jesus Christ has spoken all that is necessary through His apostles in the Bible.
Salvation is by grace alone.
God is never under any obligation to grant salvation. If God's justice required that He give grace to all men, then salvation would not be a gift but an act of justice. Salvation is through faith alone. Rather than being declared righteous on the basis of our faith plus our deeds, we are declared righteous solely on the basis of our faith in Jesus Christ. By faith, Christ's righteousness is imputed to the sinner not infused or imparted.
