By the 3rd century, with the influence of Origen, the traditions of the inherent immortality of the soul and its divine nature were established.[32] As the new Encyclopædia Britannica points out: “The early Christian philosophers adopted the Greek concept of the soul’s immortality and thought of the soul as being created by God and infused into the body at conception.”[33] Inherent immortality of the soul was accepted among western and eastern theologians throughout the Middle Ages, and after the Reformation, as evidenced by the Westminster Confession.[34][citation needed]
