I'm sure that Plotinus wasn't that impressed by the Christians.
As Plotinus tells us, we elected the body, the parents, the place, and the circumstances that suited the soul and that, as the myth says, belongs to its necessity.
Who you really are, is an immaterial soul and the body is an external thing that's sort of an encrustation your soul. So this has important implications for Plotinus' ethics, because his ethics are basically all about encouraging us to turn away from the body and turn towards these higher principles, so universal soul, universal intellect and ultimately the One.
In fact Plotinus thought not only that soul in general is eternal so that you always have soul, but he thought that each person's soul is eternal.
Before the 3rd century you're having several philosophical schools still as a going concern. You have not only the Platonists and the Aristotelians but you have Scepticism, you have Stoicism, you even have a little bit of Epicureanism. And what happens after Plotinus is that everybody becomes a Neo-Platonist. So if we then go forward to the Islamic world for example, Plotinus is immensely influential, and Neo-Platonism becomes at least one major component of mainstream Islamic philosophy as well.
Plotinus is a neo-Platonist, so he would encourage us to go back to Plato.
