The Original Language of the New Testament: Why Greek?

Introduction

One of the fundamental questions for understanding the foundational texts of Christianity lies in the choice of their original language. Although the action of the New Testament takes place primarily in Judea and Galilee — regions where the local populations were Semitic — the academic and historical consensus is clear: the original manuscripts of the New Testament were written in Koine Greek.

This study aims to analyze the historical reasons for this predominance, the internal textual evidence that confirms Greek as the source language, and to address alternative theories regarding possible Aramaic originals.

Historical Context: Greek as the Lingua Franca

In the first century, Koine Greek was not only the language of Greece but that of the entire Eastern Mediterranean. This heritage, stemming from the conquests of Alexander the Great, was maintained and strengthened under the administration of the Roman Empire.

While Aramaic remained the vernacular language of many Jews in Israel, knowledge of Greek was a vital skill for international communication and commerce. Archaeological discoveries testify to this cultural influence. For example, a study of Jewish funerary inscriptions in Judea between 300 B.C. and 500 A.D. reveals a striking statistic:

70% of inscriptions are in Greek;

12% in Latin;

only 18% in Aramaic or Hebrew.

"Jews wanted an event as solemn as their death to be immortalized in a language their contemporaries and descendants could read." (Pieter W. Van Der Horst, Jewish Funerary Inscriptions, 1992).

Linguistic Clues in Jesus' Ministry

Although Aramaic was likely Jesus' everyday language, the Gospels report several interactions where the use of Greek seems to have been the only possible linguistic bridge:

The dialogue with the Syro-Phoenician woman (Mark 7:25–30).

The exchange with the Greeks who came to the feast (John 12:20–28).

The conversations with the Roman centurion (Matthew 8:5–13) and especially the trial before Pontius Pilate (John 18:33–38), where the absence of mention of an interpreter suggests the use of Greek, the administrative and common language.

Internal Evidence of Writing in Greek

Several textual features demonstrate that the New Testament is not merely a translation from Aramaic but an original composition in Greek:

Explicit translations: On several occasions, the authors retain an Aramaic word but immediately provide the Greek translation (e.g., Talitha koum in Mark 5:41, or Golgotha in Mark 15:22). If the original text had been in Aramaic for an Aramaic-speaking audience, these clarifications would be redundant.

Untranslatable wordplay: Some passages rely on specifically Greek linguistic nuances. For example, the dialogue between Jesus and Peter in John 21:15–17 plays on the verbs agapaō and phileō (two forms of love), a distinction that Aramaic does not allow to be rendered with the same precision. Similarly, the wordplay between Petros and petra in Matthew 16:18.

Use of the Septuagint: The vast majority of Old Testament citations in the New Testament come from the Septuagint (the Greek version of the Scriptures) rather than the Hebrew or Aramaic text.

Alternative Theories and the Exception of Matthew

Some schools support the "Aramaic primacy" thesis, arguing that the original writings were those preserved in the Syriac Peshitta. They rely on the presence of Semitic structures (Hebraisms) in the Greek text. However, historians point out that these influences are natural for authors whose second language is Greek, but do not constitute proof of a translation.

The case of the Gospel according to Matthew is, however, particular. Eusebius of Caesarea, quoting Papias of Hierapolis, reports:

"Matthew compiled the sayings in the Hebrew language, and everyone translated them as he was able."

Irenaeus of Lyon supports this view, stating that Matthew published a written form of the Gospel among the Hebrews in their own language. This suggests the possible existence of a primitive version (or source) in Hebrew or Aramaic, although the text of Matthew as we possess it today has all the characteristics of an original Greek composition.

Conclusion

In conclusion, while Jesus and his disciples lived in a bilingual environment, the choice of Greek for the writing of the New Testament was a strategic and pragmatic decision. This language offered the broadest platform for the universal dissemination of the Christian message.

The predominance of the oldest Greek manuscripts, the quotations of the Septuagint, and the internal linguistic structures confirm that Koine Greek is indeed the language in which early Christian thought was fixed for posterity, with Aramaic surviving only as "memorial traces" in the text.
