The Greek philosopher Plato (born about 428 B.C.E.) had no way of knowing that his teachings would eventually find their way into apostate Christianity. Plato’s principal contributions to “Christianity” were in connection with the teachings of the Trinity and the immortality of the soul.

Regarding the immortal-soul doctrine, the “New Catholic Encyclopedia” says: “The Christian concept of a spiritual soul created by God and infused into the body at conception to make man a living whole is the fruit of a long development in Christian philosophy. Only with Origen [died about 254 C.E.] in the East and St. Augustine [died 430 C.E.] in the West was the soul established as a spiritual substance and a philosophical concept formed of its nature. . . . [Augustine’s] doctrine . . . owed much (including some shortcomings) to Neoplatonism.”—Volume XIII, pages 452, 454.
