Dogma is a principle or set of principles laid down by an authority as incontrovertibly true. It serves as part of the primary basis of an ideology or belief system, and it cannot be changed or discarded without affecting the very system’s paradigm, or the ideology itself.
They can refer to acceptable opinions of philosophers or philosophical schools, public decrees, religion, or issued decisions of political authorities.
The term derives from Greek δόγμα “that which seems to one, opinion or belief” and that from δοκέω (dokeo), “to think, to suppose, to imagine”.
Dogma came to signify laws or ordinances adjudged and imposed upon others by the First Century. The plural is either dogmas or dogmata, from Greek δόγματα.
The term “dogmatics” is used as a synonym for systematic theology, as in Karl Barth’s defining textbook of neo-orthodoxy, the 14-volume Church Dogmatics.
Dogmata are found in religions such as Christianity, Judaism, Buddhism, and Islam, where they are considered core principles that must be upheld by all believers of that religion.
As a fundamental element of religion, the term “dogma” is assigned to those theological tenets which are considered to be well demonstrated, such that their proposed disputation or revision effectively means that a person no longer accepts the given religion as his or her own, or has entered into a period of personal doubt.
Dogma is distinguished from theological opinion regarding those things considered less well-known. Dogmata may be clarified and elaborated but not contradicted in novel teachings .Rejection of dogma may lead to expulsion from a religious group.
In Christianity, religious beliefs are defined by the Church. It is usually on scripture or communicated by church authority. It is believed that these dogmas will lead human beings towards redemption and thus the “paths which lead to God”.
For Catholicism and Eastern and Oriental Orthodox Christianity, the dogmata are contained in the Nicene Creed and the canon laws of two, three, seven, or twenty ecumenical councils(depending on whether one is Nestorian, Oriental Orthodox, Eastern Orthodox, or Roman Catholic). These tenets are summarized by St. John of Damascus in his Exact Exposition of the Orthodox Faith, which is the third book of his main work, titled The Fount of Knowledge.
In this book he takes a dual approach in explaining each article of the faith: one, for Christians, where he uses quotes from the Bible and, occasionally, from works of other Fathers of the Church, and the second, directed both at non-Christians (but who, nevertheless, hold some sort of religious belief) and at atheists, for whom he employs Aristotelian logic and dialectics.
The decisions of fourteen later councils that Catholics hold as dogmatic and numerous decrees promulgated by Popes’ exercising papal infallibility (for examples, see Immaculate Conception and Assumption of Mary) are considered as being a part of the Church’s sacred body of doctrine.
Roman Catholic dogmata are a distinct form of doctrine taught by the Church.
Protestants to differing degrees affirm portions of these dogmata, and often rely on denomination-specific “Statements of Faith” which summarize their chosen dogmata (see, e.g., Eucharist).
In Islam, the dogmatic principles are contained in the aqidah. Within many Christian denominations, dogma is referred to as “doctrine”.
