“Augustine’s treatment of the soul has been enormously influential. The view that the soul is immaterial spread quickly around the Christian world of his time, thanks, in large part, to his endorsement, and it eventually became solidified Christian orthodoxy. It may seem strange to us today, but before and during Augustine’s time, the immateriality of the soul was not obvious. For some Christians, “as his fellow African Tertullian had preferred, the soul (was) material.”23 Augustine helped the immateriality of the soul to achieve its nearly universal acceptance amongst Christians (leaving liberal Protestants aside, of course). The Church also follows, and thereby legitimizes, Augustine’s judgment that the soul is a composite of body and soul.”
