Did the New Testament Authors Believe the Earth Is Flat?

Abstract

Certain scholars find evidence that the authors of the New Testament held to the cosmology of the ancient Near East, in which the sky is regarded as a solid dome over a flat earth. However, it was uncontroversial among Greco-Roman astronomers that the earth was spherical and was surrounded by a celestial sphere of stars. This article explores knowledge of the “two spheres” model of the cosmos in the first century CE, as this would have been become known to inhabitants of the Mediterranean world through education, word of mouth, popular astrology, and representations of the terrestrial and celestial spheres on sundials, coins, and public art. Based on these factors and the sophistication of their compositions, a number of contributors to the New Testament likely understood the earth to be spherical; their knowledge has exegetical and hermeneutical implications for discussions about scripture vis-à-vis modern science.
