Plato was one of the most important Greek philosophers in history. But philosophy aside, his influence on the Christian church was very profound.
It was Platos philosophy of the soul that became the only view in Christian theology (the Hebrew Old testament has no such concept). In fact the early church frequently quoted Plato and considered him their intellectual mentor.
St. Augustine, probably the most important church father said “The utterance of Plato” is the “the most pure and bright in all philosophy, scattering the clouds of error.”
Dean Inge, the famous professor of divinity, said that: “Platonism is part of the vital structure of Christian theology.” (See more about Plato’s influence here: https://blog.logos.com/2013/11/plato-christianity-church-fathers/)
