Final answer:
The Gospels make up approximately 14.8% of the New Testament by book count, meaning none of the provided options (20, 30, 40, 50) are correct. This calculation is based solely on the number of books, rather than text length or word count. All options are correct.
Step-by-step explanation:
The Gospels, which include the books of Matthew, Mark, Luke, and John, make up a significant portion of the New Testament.
To calculate the percentage of the New Testament that is comprised of the Gospels, we should consider the total number of books in the New Testament, which is 27.
The Gospels consist of 4 books out of these 27. Therefore, when calculating the percentage they represent, we use the formula: (Number of Gospel books / Total number of New Testament books) x 100, which gives us (4 / 27) x 100 ≈ 14.8%.
This indicates that none of the provided options, 20, 30, 40, or 50, are correct. It's important to note that this percentage is just based on the count of books, not on the length or word count of the texts.
Additionally, the individual contributions of the evangelists (the authors of the four Gospels) have significantly influenced Christian theology and teachings about the life of Jesus. All options are correct.
