Authority of Scripture in Christian Practice and Theology

The authority of Scripture in Christian practice and theology stems from its understanding as the "Word of God," a collection of books given by divine inspiration [1, 5]. This concept is foundational, asserting that God communicates His will to humanity through these sacred writings [3, 5]. The term "Scripture" itself, particularly in the New Testament, refers to a definite collection of sacred books regarded as divinely inspired [3].

The Bible is called the "Word of God" because its writers were considered God's instruments in conveying His will to people [5]. Consequently, whatever the inspired authors declare to be true and binding, God Himself declares to be true and binding [5]. This divine origin implies that the Word is infallible, free from error in fact, doctrine, or precept, because it was written under the guidance of the Holy Spirit [5]. Key passages like 2 Timothy 3:16 affirm this, stating that "All Scripture is God-breathed and is useful for instruction, for conviction, for correction, and for training in righteousness" [6, 7]. This "God-breathed" nature (Greek: theopneustos) signifies that God is fully responsible for the content, even while human authors were actively involved [9].

The concept of "canon" further defines the authoritative scope of Scripture. Originally meaning a straight rod or a rule, "canon" came to denote the collection of books that form the original and authoritative written rule for the faith and practice of the Christian Church, encompassing both the Old and New Testaments [2, 4]. A book is considered to have canonical authority if it has a right to be included with other books containing divine revelation, a right that does not arise from ecclesiastical authority but from its inherent nature as God's revealed will [4].

Jesus Christ Himself sanctioned the authority of the Scriptures by appealing to them, teaching from them, and referring to them as the "Word of God" [1, 12]. For instance, in Matthew 4:4, Jesus responds to temptation by quoting Deuteronomy, stating, "It is written" [12]. This demonstrates His affirmation of the Old Testament's authority. The apostles also upheld this view; Peter refers to prophetic writings as "a more sure word of prophecy" [10].

The authority of Scripture extends to both doctrine and practice. It is considered the true source for all authority in matters of belief and conduct [8]. The Scriptures are described as holy, just, and good, providing instruction in righteousness and teaching believers to live soberly, righteously, and godly [13]. They are also called the "word of truth" because they originate from the God of truth, contain nothing but truth, and are faithful sayings [14]. All saving knowledge is understood to be obtained from the Word of God [5].

Historically, the recognition of Scripture's authority developed as God raised up individuals to commit His revelation to writing in an infallible record [3]. This collection of sacred writings was enlarged over time, culminating in the completed Old and New Testaments [3]. The early Church, as evidenced by Amphilochius around 380 A.D., began to apply the term "canon" directly to the Scriptures, indicating their role as the rule of faith [2]. The Old Testament prophets, for example, spoke and wrote under the influence and direction of the Spirit of God, foretelling events that proved the truth of the Gospel [10]. The Psalms also refer to the law as a "testimony" of the divine will and the Scriptures as testifying of Christ [11].

The word canon, in classical Greek, is properly a straight rod, "a rule" in the widest sense, and especially in the phrases "the rule of the Church," "the rule of faith," "the rule of truth," The first direct application of the term canon to the Scriptures seems to be in the verses of Amphilochius (cir. 380 A.D.), where the word indicates the rule by ”

It was God's purpose thus to perpetuate his revealed will. From time to time he raised up men to commit to writing in an infallible record the revelation he gave. The "Scripture," or collection of sacred writings, was thus enlarged from time to time as God saw necessary. We have now a completed "Scripture," consisting of the Old and New Testa”

This word is infallible, because written under the guidance of the Holy Spirit, and therefore free from all error of fact or doctrine or precept. (See [670]INSPIRATION; [671]BIBLE.)

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.
