This is almost entirey wrong as to data and reasoning.
The stupidest part of your post is that appeal to Greek philosophical notions. Aristotle and Plato both opposed those notions based on their Rationial knowledge of God and their knowledge of why Homer and Hesiod and others taught as they did.
Not only that the line of progress is from the Jewish Faith backwards to Greece via the Septuagint and the recognition of the Christian elements in Plato in others.
As to the greek elements validated by Christianity

Plato and the Christians: Passages from the writings of Plato
by Plato (Author), Adam Fox (Introduction)
NOtice that the great haters of Christianity like Celsus argued sincerely that Jesus had stolen His teaching from Plato.
“The utterance of Plato, the most pure and bright in all philosophy, scattering the clouds of error . . .”
“I found that whatever truth I had read [in the Platonists] was [in the writings of Paul] combined with the exaltation of thy grace.”
