Final answer:
The New Testament, including the four gospels, was originally written in Greek. It later was translated into Latin in the form of the Vulgate, which became the main edition in Europe for many centuries.
Step-by-step explanation:
The books that make up the New Testament were written in Greek. This was during a time when Greek was not only a language of daily life in the eastern parts of the Roman Empire but also the language of the church and the state. Following the tradition of Jewish intellectual legacy, translations from Hebrew and Aramaic into Greek were made, enabling Greek-speaking Christians to have access to the texts, which included the crucial gospels of Matthew, Mark, Luke, and John. These gospels, along with other books, were initially shared orally and later committed to writing around 90 CE. Saint Jerome eventually produced the Vulgate, a Latin version of the Bible, which became the main edition for Europe until the sixteenth century.
