Using Extrabiblical Examples in Theological Development Safely

Theological development often draws upon examples beyond direct biblical commands to illustrate and reinforce Christian principles. These extrabiblical examples, while not carrying the same authority as scripture, can serve as powerful illustrations of godly living and warnings against sin.

One common use of extrabiblical examples is in demonstrating virtues. For instance, the Torrey's Topical Textbook identifies Christ as an example of self-denial, sincerity, liberality, and early rising, citing various New Testament passages [1, 2, 3, 4]. While these are biblical examples, the principle extends to figures outside the immediate scriptural narrative. For example, Calvin, in his commentary on Genesis, praises a woman for her "more than masculine mind" and modesty in enduring and repelling attacks, holding her up as an example for men to emulate [9]. He also notes the contagion of "evil examples," suggesting that observing the conduct of others, whether good or bad, influences behavior [10]. These examples, though not explicitly commanded in scripture, serve to illustrate and encourage specific virtues or warn against vices.

Another application involves understanding the nature of sin. While the Bible clearly defines sin, extrabiblical observations can help clarify its manifestations. For instance, the Jamieson, Fausset & Brown commentary on Proverbs 30:8 interprets "vanity" as encompassing "all sorts of sinful acts" [6]. Similarly, the Tyndale House commentary on Psalms 58:3 notes that while all humans are born sinners, the wicked indulge their sinful nature, whereas the godly fight against it [5]. This distinction, while rooted in biblical texts like Romans 7:19-23, is a theological observation about human behavior that can be informed by broader human experience. Augustine, as cited in Jamieson, Fausset & Brown, clarifies that while one can be "born of God," the devil does not "beget" children but rather those who imitate him become his children through corruption, not birth [7]. This theological distinction uses an analogy of birth and imitation to explain a spiritual reality.

The use of extrabiblical examples also extends to understanding the consequences of actions. The Tyndale House commentary on Hebrews 12:1 uses the Greco-Roman literary metaphor of a race to explain the need for endurance in faith, comparing sin to "extra weight" that hinders a runner [11]. This analogy, while not biblical in origin, effectively communicates a biblical truth about spiritual discipline. Similarly, the Tyndale House commentary on Romans 1:18 describes God's anger not as a spontaneous emotional outburst, but as a "necessary response to sin," a theological understanding that can be observed in the patterns of divine judgment throughout history, both biblical and extrabiblical [8].

In all these cases, extrabiblical examples function as illustrations or analogies that deepen understanding of biblical truths, rather than as independent sources of doctrine. They help to make abstract theological concepts more concrete and relatable, providing practical insights into Christian living and the nature of God and humanity.

  5. Psalms (Protestant academic) “Tyndale House on Psalms 58:3: 58:3 All human beings are born sinners (see 51:5); however, whereas the wicked indulge their sinful nature, the godly fight against it (Rom 7:19-23; Jas 4:1-10).”

He is a son of the devil (Jo1 3:10; Joh 8:44). John does not, however, say, "born of the devil." as he does "born of God," for "the devil begets none, nor does he create any; but whoever imitates the devil becomes a child of the devil by imitating him, not by proper birth" [AUGUSTINE, Ten Homilies on the First Epistle of John, Homily 4.10]. From the devil there is not generation, but corruption [BENGEL]. sinneth from the beginning--from the time that any beg”
  8. Romans (Protestant academic) “Tyndale House on Romans 1:18: 1:18–3:20 Paul delays exploring the theme of righteousness through faith (see 3:21) until after he first teaches about universal sinfulness. Gentiles (1:18-32) and Jews (2:1–3:8) are equally under sin’s power and cannot find favor with God by any action of their own (3:9-20). 1:18 God’s anger is not a spontaneous emotional outburst, but the holy God’s necessary response to sin. The Old Testament often depicts God’s anger (Exod 32:10-12; Num 11:1; Jer 21:3-7) and predicts a decisive outpouring of God’s wrath on human sin at the end of history. While Paul usually de”
