الأقانيم الثلاثة بين اوغسطين و توما الأكويني، و أصولها الأفلوطينية

الملخص EN

We are trying in this research to shed light on a belief that took a space at that time.

In the consideration of what many people believed in it, not only the common people, but even many philosophers, specifically Augustine and Thomas Aquinas, and how the doctrine of the hypostases, this belief is alien to Christians and how it was taken from Phlotinism and also from some ancient Greek philosophies.

What are the evidences of its proof and what are the evidences of its invalidity, how did it affect the Christians, how did it enter into their faith, how was Plato the first to introduce this term, how did Augustine interpret it and what did Aquinas say about it, is there a difference between them, are they in agreement by saying it or they are in the conflict.
