John Frame argues (ST, 27-29) that God’s covenant transcends “all other loyalties.” As Lord of the covenant, he forbids allowing someone else to be Lord. Examples of this principle of loyalty abound in the New Covenant, but in particular, Matthew 8 and 10 argue for the supremacy of discipleship even over familial claims.
The Lordship of Jesus forms, therefore, the principle inherent in Sola Scriptura. While parents may play a role in shaping our understanding of life, our supreme authority is still to the Lord (Acts 5:29). Sola Scriptura does not compete with anyone else for authority. She is the ultimate authority, as Christ is the ultimate Lord.
Since he controls all things, therefore, he has the right to demand all obedience from his own and his creation. Human obedience becomes the means through which we show forth our loyalty to God above all earthly loyalties.
Thus, God’s authority covers all areas of human existence (28):
God claims the authority to direct all our thinking and all our decisions. The Lord is totalitarian, as only he has the right to be (28).
