The term, “Abrahamic Religions” has an origin in the Qur’an, referring to the faiths of Islam, Christianity, and Judaism at the time it is written. A common basis of comparison is between the texts of the faiths.
Point of Comparison (the Bible)
The term, “Christianity” has its root in the name, “Christians” whom the people of Antioch (sometime before 62-64 AD) called the followers (disciples) of Jesus Christ as. To date, quite a number of organized religious denominations are attributed to the term, “Christianity”. Historically, there are varied sums of books treated as the sacred text, some 66, some 73, some 81, etc.
For the purpose of comparison, only 66 books (table above) are used as the standard Bible.
Judaism & Christianity
The term, “Judaism” has its root in the name, “Judah” which is attributed after the tribe (or descendants) of Judah. To date, quite a number of organized religious movements are attributed to the term, “Judaism”. One of the earlier foundational texts is known as Tanakh, which is an abbreviated form of “TaNaKh” (3 capital letters, T N K = 3 categories of books). Comparatively, the same texts in the Tanakh are also found in the Bible (Old Testament section).
Despite the varied orders and compilations (as shown above), the texts are almost identical, and both carry the same message. The message is that there is an expectation of a Savior (Messiah) for the salvation of mankind.
Islam & Christianity
The term, “Islam” has an origin in the Arabic word, “salam” which has certain attributes of “peace”, “safety”, “submission”, etc. To date, quite a number of organized religious schools are attributed to the term, “Islam”. The foundational Islamic text is known as the Qur’an, which is a collection of 114 chapters in the order of length (roughly). In contrast to the Bible (with books, and then chapters, then verses), the Qur’an consists of only chapters (surah), and then verses (ayat).
Reference: List of chapters in Qu’ran.
Given that there is no overlap of verses between the texts, only commentaries about the Bible are found in the Qur’an.
Accordingly, the Qur’an acknowledges certain categories of books in the Bible (Pentateuch or Mosaic Law/Tawrat, Psalms/Zabur, Gospel/Injil) as trustworthy. See The Qur’an says the Bible is not corrupt.
From the Qur’an’s standpoint, the rest of the biblical texts testify of certain individuals about their existence, though in different narrations. (Example: ‘Similarities between the Bible and the Qur’an‘).
Apart from the commentaries, Islamic doctrine does not align completely with the Bible unless one looks at the central figure — Jesus Christ. See Jesus and Islam.
