Sources of Revelation is a theological expression for the divine origin and ecclesial transmission of revealed truth, which comes from the one God and reaches the Church through Sacred Scripture and Sacred Tradition as intimately united and distinct modes.[1]
One divine source and one deposit
God himself is the first source of revelation. The Father speaks his eternal Word and sends the Holy Spirit so that human beings may share divine life. Revelation is therefore one in origin, Christological in fullness, and ordered to one saving end. Scripture and Tradition do not originate separate religions, and neither is an independent store of information capable of being interpreted apart from the one apostolic faith.[2]
Dei Verbum teaches that Sacred Tradition and Sacred Scripture flow from the same divine wellspring, merge into a unity, and tend toward the same end. Together they form one sacred Deposit of Faith committed to the Church. This conciliar language supplies the governing rule for the older theological question of whether revelation has one source or two: any acceptable terminology must preserve both the single divine origin and the real distinction between the two forms of transmission.[3][4]
Fount, content, and means
The word source can name different things. It may mean God as revealer, Christ as the fullness of revelation, the apostolic Gospel as entrusted content, or Scripture and Tradition as the means by which that content is handed on. Arguments become confused when one sense is counted against another. Saying there is one divine fount does not collapse Scripture into Tradition; saying there are two modes does not divide the Word of God into unrelated deposits.
Scripture and Tradition
Sacred Scripture is the speech of God put into writing under the breath of the Holy Spirit. Its inspiration gives the canonical books a unique status not possessed by later ecclesiastical texts. Sacred Tradition is the living transmission of the Word entrusted by Christ and the Spirit to the apostles, perpetuated in their successors and in the Church's doctrine, life, and worship. Tradition communicates the apostolic inheritance in its integrity rather than functioning only as a list of propositions absent from the Bible.[5]
The two are mutually ordered. The Church receives the canon of Scripture within apostolic Tradition, celebrates Scripture in the liturgy, and reads it according to the faith that produced and received the canon. Scripture normatively bears inspired witness within the same Tradition and tests claims falsely presented as inherited faith. The Church does not draw certainty about every revealed truth from Scripture alone, yet no authentic Tradition can contradict the inspired Word.
Material sufficiency and the two-source formula
Catholic theologians have debated whether all revealed truths are contained in Scripture at least implicitly, a view often called material sufficiency, or whether some are transmitted through Tradition in a stronger content-distinct sense. The Magisterium has not made every scholastic formulation the rule of faith. The binding doctrine is that Scripture and Tradition are both divinely ordered, closely connected, and to be received with equal loyalty and reverence; a theory may not render either dispensable.
The Magisterium and theological evidence
The Magisterium is not a third source of revelation alongside Scripture and Tradition. It has the task of authentically interpreting the Word of God, whether written or handed on, and exercises that office in the name of Jesus Christ. It listens to the Word, guards it, and explains it faithfully. Dogmatic definitions can state revealed truth with binding precision, but their authority serves the received deposit rather than supplying a new revelation from ecclesiastical power.
Theology consults many witnesses: biblical texts, creeds, councils, papal teaching, Fathers, liturgies, canon law, the consensus of the faithful, saints, and historical scholarship. These are not all sources of revelation in the same formal sense or at the same level of authority. They provide evidence for Scripture's meaning, Tradition's content, doctrinal development, ecclesial reception, or disciplined theological reasoning. Exact citation must identify what a witness proves instead of flattening every Catholic document into an equivalent source.
Different from historical source criticism
In biblical studies, sources can also mean earlier documents, oral units, or traditions used by a human author. Source criticism in that sense is a historical method, not a doctrine that revelation comes from multiple divine origins. Responsible scholarship may investigate literary dependence and composition while receiving the final canonical books as inspired wholes. The theological Sources of Revelation question concerns how God's apostolic Word is given and transmitted to the Church.
