I tried to download the YouTube video clip from the 2003 film Luther, that contains Luther's speech at the Diet of Worms. So I will post the link to it instead. I highly encourage you to head over there and check it out. It really is stirring. Click here to watch.
The following text is from Answers in Genesis.
The 5 Solas of the Reformation
Though widely known a generation ago, the five solas are frequently overlooked in the modern church. Each is a Latin phrase. When taken together, they summarize the teaching of the Reformation. They stress the positive aspect of the truth and how the medieval church distorted the truth.
This sola expresses the conviction that all teaching of the church for doctrine and practice must be built upon that which is revealed in Scripture or deduced by good and necessary consequence from the Scripture. So the Word of God is the supreme and final authority. It alone has the power to bind the conscience.
Sola gratia (Grace alone)
Salvation comes by the free grace of God. Man cannot—and need not—do any work to earn God’s favor. Salvation is not based in any way upon human merit.
Solus Christus (Christ alone)
Christ is the only mediator between God and man. Thus an individual can go directly to God through Christ.
Sola fide (Faith alone)
Faith in the Person of Christ is the instrumental means of salvation. The Roman Catholic Church taught that, while initial grace was infused at baptism, the person had to cooperate with that grace until God accepted him as righteous.
Soli Deo Gloria (for God’s glory alone)
Salvation is exclusively God’s work, and so He alone is worthy to receive praise and thanksgiving. This sola expresses the highest motive for all the Christian’s deeds—the glory of God alone.
Let us praise God for the light of His Word!
"The entrance of Thy words giveth light..." (Psalm 119:130)
