Christian Cosmology
Biblical cosmology is the biblical writers’ conception of the cosmos as an organised, structured entity, including its origin, order, meaning and destiny. The Bible was formed over many centuries, involving many authors, and reflects shifting patterns of religious belief; consequently, its cosmology is not always consistent. Nor do the biblical texts necessarily represent the beliefs of all Jews or Christians at the time they were put into writing: the majority of the texts making up the Hebrew Bible or Old Testament in particular represent the beliefs of only a small segment of the ancient Israelite community, the members of a late Judean religious tradition centered in Jerusalem and devoted to the exclusive worship of Yahweh.
The ancient Israelites envisaged the universe as a flat disc-shaped Earth floating on water, heaven above, underworld below. Humans inhabited Earth during life and the underworld after death; there was no way that mortals could enter heaven, and the underworld was morally neutral; only in Hellenistic times (after c. 330 BCE) did Jews begin to adopt the Greek idea that it would be a place of punishment for misdeeds, and that the righteous would enjoy an afterlife in heaven. In this period too the older three-level cosmology in large measure gave way to the Greek concept of a spherical Earth suspended in space at the center of a number of concentric heavens.
The opening words of the Genesis creation narrative (Genesis 1:1–2:3) sum up the biblical editors’ view of how the cosmos originated: “In the beginning God created the heavens and the earth”; Yahweh, the God of Israel, was solely responsible for creation and had no rivals, implying Israel’s superiority over all other nations.
Later Jewish thinkers, adopting ideas from Greek philosophy, concluded that God’s Wisdom, Word and Spirit penetrated all things and gave them unity. Christian traditions then adopted these ideas and identified Jesus with the Logos (Word): “In the beginning was the Word, and the Word was with God, and the Word was God” (John 1:1). Interpreting and producing expositions of biblical cosmology was formalized into a genre of writing among Christians and Jews called the Hexaemal literature. The genre entered into vogue in the second half of the fourth century, after it was introduced into Christian circles by the Hexaemeron of Basil of Caesarea.
