"God is a superior trinity of Father, Son and Spirit. Man is an inferior trinity of spirit, soul (mind) and body (flesh). If a man's spirit is alive and uppermost, he has fellowship with God. If a man's flesh is uppermost, his fellowship with God is broken, because God wants nothing to do with his sinful flesh. Man can only meet God in the spirit."
Please leave your guess in the comments section below. No google searches or cheating! I'll post the answer next week (Lord willing).
No, this is not from Plotinus. It is from Chuck Smith's The Gospel According to Grace (1981), a brief commentary on Romans which was very influential in the early years of Calvary Chapel.
