- Sola Scriptura: Scripture alone is the only infallible rule of faith (or the spiritual standard) for the church. Thus, they function as the ultimate authority in spiritual matters.
- There are other legitimate (but lesser) "rules of faith" such as the writings of the church fathers, traditions, church councils, catechisms, and godly leaders of the church (but only Scripture is infallible).
- Perspicuity of Scripture (more on this in future articles):
- Detailed Biblical Case for the Ultimate Authority and Formal Sufficiency of The Scriptures:
-Certainty of the Lord's action and teachings (Luke 1:1-4)
-Life in the name of Jesus Christ (John 20:30-31)
-Instructions to salvation (2 Timothy 3:15)
-Commandments of the Lord (1 Corinthians 14:37)
-Standard through which Jesus will judge (John 12:48; James 2:12; Revelation 20:12)
-Standard to which nothing can be added (Deuteronomy 4:2; Proverbs 30:5-6; Revelation 22:18-19)
-Extra-biblical doctrinal development is condemned (Galatians 1:8-9; 1 Timothy 1:3-4; 2 John 9-11)
-Proper conduct in the church (1 Timothy 3:14-15)
-Protection against sin (Matthew 4:1-11; 1 John 2:1)
-Every good work (2 Timothy 3:16-17)
-Life (Psalm 19:7-14; 2 Peter 1:3-4)
-Joy that is complete (1 John 1:1-4)
-Hope and encouragement (Romans 15:4)
-Standard by which we learn spiritual lessons (1 Corinthians 10:11)
-Standard by which prophets/ministers are tested (Isaiah 8:16-20; Acts 17:11-12)
+ Jesus always used the Scriptures as the measuring stick for determining Truth.
+ Even though the apostles were inspired by genuine oral revelation, they always directed people to the Scriptures for the final determination of truth.
-Blessings from God (Revelation 1:3)
-Standard that judges traditions (Matthew 15:1-9; Mark 7:1-13)
-Standard which we cannot go beyond (1 Corinthians 4:6)
-Scripture is how we are reminded of apostolic oral traditions, thereby proving that they have been replaced by Scripture (2 Peter 3:1-2)
+Although traditionalists claim extra-biblical oral tradition, they cannot come up with even one phrase of what Jesus Christ or the apostles said, that is not recorded in Scripture.
