Scriptural Authority and Source Credibility in Theology

Scriptural authority in theology refers to the belief that the Bible is the ultimate source of truth and guidance for Christian faith and practice [6]. This authority stems from the conviction that the Scriptures are "given by inspiration of God" (2 Timothy 3:16) [4, 9]. The apostle Paul states that "all Scripture is God-breathed" (2 Timothy 3:16), indicating that God is the ultimate source of the biblical text, even while acknowledging the active involvement of human authors [9]. This divine inspiration applies to the Hebrew Scriptures (Old Testament) and is understood to extend to the New Testament as well [9].

The credibility of Scripture as a theological source is rooted in its divine origin. The Bible is described as the "word of God," the "word of Christ," and the "word of truth" [4]. Christ himself sanctioned the Scriptures by appealing to them and teaching from them [4]. The apostle Peter further emphasizes the reliability of prophetic writings, stating that they are "more sure" than personal testimonies, even those of eyewitnesses [8]. This suggests that the written word of prophecy holds a unique and firm authority [8].

The concept of scriptural authority is foundational across various Christian traditions. For instance, the Presbyterian tradition affirms that Scripture is "the true source of all authority in questions of doctrine and practice" [6]. John Gill, a Baptist/Reformed commentator, notes that the "faith of God's elect" is firm and immovable, supported by God's power and Christ's mediation, and cannot be overthrown by false teachers, unlike a merely historical faith [7]. This highlights the enduring and reliable nature of the truths found in Scripture.

The Bible's authority is not merely intellectual assent but also calls for obedience and trust. Faith, in general, is described as the persuasion that a statement is true, and it involves trust [5]. This faith is produced by teaching and can lead to full assurance [5]. The purpose of apostolic preaching, as articulated by Paul, is "so that they will believe and obey him" [10]. This connection between belief and obedience underscores the practical implications of scriptural authority.

The Scriptures are understood to be effective in providing wisdom for living out salvation [9]. They are not only a source of doctrine but also a guide for righteous living. For example, the psalmist connects walking in the law of the Lord with blessedness (Psalm 119:1) [1]. The apostle Paul encourages believers to "abstain from Gentile pollutions" because they belong to God, who is holy [6]. This demonstrates how scriptural commands are tied to God's character and His desire for His people to reflect His holiness [6].

The power of God, described in various biblical passages, undergirds the authority of His word [2]. God's power is characterized as great, strong, glorious, mighty, everlasting, sovereign, effectual, irresistible, and incomparable [2]. This divine power ensures the efficacy and truthfulness of the Scriptures. The assurance that believers can have regarding their election, redemption, adoption, and salvation is rooted in the unalienable love of God and union with Christ, all of which are revealed through the divine word [3].

  5. Easton's Bible Dictionary “Easton's Bible Dictionary: Faith — Faith is in general the persuasion of the mind that a certain statement is true (Phil. 1:27; 2 Thess. 2:13). Its primary idea is trust. A thing is true, and therefore worthy of trust. It admits of many degrees up to full assurance of faith, in accordance with the evidence on which it rests. Faith is the result of teaching (Rom. 10:14-17). Knowledge is an essential element in all faith, and is sometimes spoken of as an equivalent to faith (John 10:38; 1 John 2:3). Yet the two are distinguished in this respect, that faith includes in it assent, which is an act ”

Paul was speaking of the Hebrew Scriptures (the Old Testament), but his statement can now apply to all Scripture, including the New Testament (see, e.g., 2 Pet 3:15-16). 3:16 The fact that Scripture is inspired by God (literally God-breathed, breathed out by God’s own speech; see also Heb 4:12-13; 2 Pet 1:20-21) does not negate the active involvement of the human authors. But it does affirm that God is fully re”
