Authority of Scripture in Christian Decision Making

The authority of Scripture in Christian decision-making stems from its nature as the "Word of God," given by divine inspiration and serving as the authoritative rule for faith and practice ^{[2, 4]}. Christians believe that God communicates His will to humanity through the Bible, making its declarations true and binding ^[4].

The term "canon" itself, derived from a Greek word meaning "a straight rod" or "rule," was applied to the Scriptures to signify their role as the authoritative standard for doctrine and duty ^{[2, 3]}. This authority is not derived from ecclesiastical endorsement but from the inherent nature of the books as a revelation of the divine will ^[3]. The Apostle Paul emphasizes this, stating that "all Scripture is given by inspiration of God" (2 Timothy 3:16 KJV), meaning it is "God-breathed" ^{[1, 11]}. This divine origin ensures that the Scripture is infallible, free from error in fact, doctrine, or precept, because it was written under the guidance of the Holy Spirit ^[4].

The Bible is referred to by various names that underscore its authority, including "the Word," "Word of God," "Word of Christ," "Word of truth," "Holy Scriptures," and "Scripture of truth" ^[1]. These titles highlight its divine origin and its role as a source of truth and guidance. For instance, the Geneva Bible translation of 2 Timothy 3:15 states that the "holy Scriptures... are able to make thee wise vnto saluation, through the faith which is in Christ Iesus" ^[7]. This indicates that the Scriptures provide the necessary wisdom for salvation and for living a life of faith ^{[7, 11, 13]}.

The authority of Scripture is foundational for Christian decision-making because it provides the principles and commands that guide believers. John Chrysostom notes that God assures people that His commandments are not beyond their power to obey, bringing truth and duty near to them through the apostolic message ^[9]. The Scriptures are seen as the "true source of all authority in questions of doctrine and practice" ^[10]. This means that when faced with decisions, Christians are to consult the Bible for direction.

Decision-making in the Christian life is often presented as a necessary aspect of serving God ^[6]. The Scriptures provide guidance for this, encouraging believers to seek God with their heart, keep His commandments, and follow Him fully ^[6]. The concept of "faith" itself, which is central to Christian life, involves the persuasion that a statement is true and worthy of trust ^[5]. Since the Scriptures are considered the infallible Word of God, they are the ultimate object of this trust in matters of belief and conduct ^{[4, 5]}.

The New Testament writers frequently appealed to the Old Testament Scriptures to establish the truth of their teachings. Jesus Himself sanctioned the Scriptures by appealing to them and teaching from them ^[1]. The Apostle Paul, in Romans 14:23, states that "whatever is not of faith is sin," implying that decisions should be rooted in faith, which is informed by God's revealed will in Scripture ^[8]. The revelation of God's mystery, once kept secret, is now made known through the prophetic Scriptures for the "obedience of faith to all the nations" ^[8]. This underscores the idea that the Scriptures are given not just for knowledge, but for practical obedience in daily life.

The human authors of Scripture were actively involved in its writing, but God is fully responsible for its content, ensuring its divine authority ^[11]. This divine inspiration means that the Scriptures testify to God's will and provide saving knowledge ^{[4, 12]}. Therefore, for Christians, the Bible serves as the ultimate guide for discerning God's will and making decisions that align with His purposes.

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 ”
Easton's Bible Dictionary “Easton's Bible Dictionary: Canon — This word is derived from a Hebrew and Greek word denoting a reed or cane.

A book is said to be of canonical authority when it has a right to take a place with the other books which contain a revelation of the Divine will.

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.)

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.
