The rule of faith (Greek: κανών της πίστης, Latin: regula fidei) is the name given to the ultimate authority or standard in religious belief. It was used by Early Christian writers such as Tertullian. The phrase is sometimes used for early creeds.
As a standard for adherence to orthodoxy, rule of faith originally referred to the Old Roman Symbol, which was an earlier and shorter version of the Apostles' Creed and other later statements of faith. As a historical standard for adherence to orthodoxy, rule of faith may also refer to other statements of faith including the Nicene Creed, Athanasian Creed, Augsburg Confession, Articles of Dort, Westminster Confession and others, the inner light of the spirit, as among mystics.
The rule of faith is the name given to the ultimate authority or standard in religious belief, such as the Word of God (Dei verbum) as contained in Scripture and Apostolic Tradition, as among Catholics; theoria, as among the Eastern Orthodox; the Sola scriptura (Bible alone doctrine), as among some Protestants; the Wesleyan Quadrilateral of faith, which held that Scripture, tradition, reason, and experience, as among other Protestants; and reason alone, as among Rationalist philosophers.
Second century usage
…this faith: in one God, the Father Almighty, who made the heaven and the earth and the seas and all the things that are in them; and in one Christ Jesus, the Son of God, who was made flesh for our salvation; and in the Holy Spirit, who made known through the prophets the plan of salvation, and the coming, and the birth from a virgin, and the passion, and the resurrection from the dead, and the bodily ascension into heaven of the beloved Christ Jesus, our Lord, and his future appearing from heaven in the glory of the Father to sum up all things and to raise anew all flesh of the whole human race…— Irenaeus, Adversus Haereses
"Therefore, lest we suffer any such thing, we must keep the rule of faith unswervingly…" [the footnote: A common expression in Irenaeus, designating the model of faith which is received in baptism (cf.Against Heresies 1:9:4), and which epitomizes the "order and connection of the Scriptures." Cf. Note to Dem. 1; AH 1:8 1–10:3 (in the 1st footnote: ""the rule of faith," "order and connection" of Scripture, and "body of truth" are used to speak of the same thing).
Third century usage
Tertullian uses the phrases "rule of faith" and "rule of truth" in On Prescription Against Heretics:
Let our "seeking," therefore be in that which is our own, and from those who are our own, and concerning that which is our own, – that, and only that, which can become an object of inquiry without impairing the rule of faith.
Pope Pius XII in Humani generis uses the term analogy of faith to say that Holy Scripture should be interpreted according to the mind of the Church, not that the teaching of the Church and Fathers should be interpreted by some theorised norm of the Scriptures.
In the Catholic Church, the Bible and sacred tradition (that is, things believed to have been taught by Jesus and the apostles that were not recorded in the Bible but were transmitted through the church) are considered a rule for all believers for judging faith and practice. The current Catechism of the Catholic Church says, "all that has been said about the manner of interpreting Scripture is ultimately subject to the judgement of the Church which exercises the divinely conferred commission and ministry of watching over and interpreting the Word of God
Q. 561. Must we ourselves seek in the Scriptures and traditions for what we are to believe? A. We ourselves need not seek in the Scriptures and traditions for what we are to believe. God has appointed the Church to be our guide to salvation and we must accept its teaching us our infallible rule of faith.
...while in the Church we greatly venerate the sacred Scriptures, the Christian faith is not a 'religion of the book': Christianity is the 'religion of the word of God,' not of 'a written and mute word, but of the incarnate and living Word' (qtd. from St. Bernard of Clairvaux). Consequently the Scripture is to be proclaimed, heard, read, received and experienced as the word of God, in the stream of the apostolic Tradition from which it is inseparable
In some Protestant theology, it is a hermeneutical rule of interpreting the Bible that scripture is to interpret scripture (Sacra Scriptura sui interpres: sacred Scripture is its own interpreter). It is an understanding that enforces the Bible as the inspired Word of God, and it is therefore consistent and coherent since God cannot contradict himself.[b]

The part before "in one God" can be translated "For the Church, spread throughout the whole world to the uttermost parts of the earth, having received from the Apostles, and their disciples, the faith…". The part after "the whole human race" can be translated, "so that to Christ Jesus our Lord, and God, and Saviour, and King, according to the pleasure of the invisible Father, every knee may bow of those in the heavenly places and those on earth and those under the earth, and every tongue may confess to him, and he may do righteous judgement among all; and send the spirits of wickedness, and transgressing angels, and those who are in apostasy, and the impious, and unrighteous, and lawless, and blasphemous among men to eternal fire; but to the righteous, and holy, and those who have kept his commandments, and have persevered in his love whether from the beginning or out of repentance, granting life he may graciously give incorruption, and may put them in possession of eternal glory." Book 1, Chapter 2
- The rule of faith (Latin: regula fidei) or analogy of faith (analogia fidei) is a phrase rooted in the Apostle Paul's admonition to the Christians in Rome in the Epistle to the Romans 12:6, which says, "We have different gifts, according to the grace given us. If a man's gift is prophesying, let him use it in proportion to his faith." (NIV, 1984) The last phrase, "in proportion to his faith" is in Greek κατὰ τὴν ἀναλογίαν τῆς πίστεως ("analogy of faith"). In Romans 12:6 this refers to one of three possible ideas: the body of Christian teachings, the person's belief and response to the grace of God, or to the type of faith that can move mountains. In conservative Protestantism Romans 12:6 is viewed as the biblical reference for the term "analogy of the faith" (i.e., αναλογἰα τῆς πἰστεως).
The Bible alone is considered the word of God and the only infallible standard for judging faith and practice; hence, for conservative Protestantism, the analogy of the faith is equivalent to the analogy of scripture – that is, opinions are tested for their consistency with scripture, and scripture is interpreted by the Holy Spirit speaking in scripture (compare sola scriptura). The analogy of faith, which was advanced by Augustine of Hippo, is sometimes contrasted with the analogy of being (Latin: analogia entis), which, according to Thomas Aquinas, allows one to know God through analogy with his creation.
