The Sufficiency of Scripture in Christian Decision Making
The doctrine of Scripture's sufficiency holds that the Bible contains all knowledge necessary for salvation and Christian living, though traditions differ on how this principle applies to practical decision-making. Paul writes to Timothy that "from infancy you have known the Holy Scriptures, which are able to make you wise for salvation through faith in Christ Jesus" [5], establishing Scripture's adequacy for the central purpose of the Christian life. The text further declares that all Scripture is "inspired by God" (literally "God-breathed") and is "profitable for teaching, for reproof, for correction, for training in righteousness" [1, 9].
Biblical Foundation and Scope
Scripture presents itself as the authoritative written rule governing Christian faith and practice [3]. The canon functions as "the rule of the Church" and "the rule of faith" [3], terms that emerged in the patristic period to distinguish authoritative texts from other religious writings. Paul's language in 2 Timothy 3:16-17 indicates that Scripture equips believers comprehensively for "every good work" [9], though the scope of this equipment has been understood differently across traditions.
The sufficiency principle does not claim human self-sufficiency in interpreting or applying Scripture. Paul explicitly states, "Not that we are sufficient of ourselves, to think anything, as of ourselves: but our sufficiency is of God" [4, 8]. John Gill's Baptist commentary emphasizes that believers are "not sufficient of ourselves" for "any spiritual work whatever; not even to think anything as of ourselves" [8]. This dependence on divine enablement qualifies how sufficiency operates in practice.
Application to Decision-Making
Scripture calls for decisiveness in following God's revealed will. The concept of decision in biblical usage involves "seeking God with the heart," "keeping the commandments of God," and "following God fully" [2]. This decisiveness stands "opposed to a divided service" and "halting between two opinions" [2]. Matthew Henry's Puritan commentary on Psalm 119 notes that "those who will make anything to purpose of their religion must first make it their serious and deliberate choice" of "the way of truth" [10], grounding practical decisions in Scripture's moral framework.
Eastern Orthodox tradition, represented by Chrysostom, emphasizes Scripture's "elevating power" and role as "safeguard of the soul" [6], while also situating biblical interpretation within the Church's liturgical and patristic context. The Methodist tradition, through Adam Clarke, stresses that Timothy's early formation in Scripture enabled him to "compare its doctrines with all that had been typified and predicted" [7], suggesting that sufficiency includes the capacity to test teaching against biblical precedent.
