Augustine considers the Neoplantonists influential in his journey to understanding the nature of God's presence and the nature of sin.

C. S.  Lewis describes the parallel ideas and their difference in motivation quite beautifully.

"Christians and Platonists both believe in an 'other' world . . . for a Plantonist the contrast is usually that between an original and a copy, between the real and the merely apparent. . . for a Christian, between the eternal and temporal, or the perfect and the partially spoiled. The essential attitude of Platonism is aspiring or longing . . . In Christianity, however, the human soul is not the seeker but the sought: it is God who seeks, who descends from the other world to find and heal Man; the parable about the Good Shepherd looking for and finding the lost sheep sums it up" (qtd. in Ryken 53).
