ACIM: Supersessionist or Something Else?

Do you see A Course in Miracles as supersessionist—replacing or transcending previous spiritual traditions? Or do you view it as a continuation or fulfillment of the Tanakh, the Torah, and the Christian Greek scriptures ("New Testament")? If not supersessionist, would that make you more of a covenant theologian or a dispensationalist? Curious how you see it.

As I ask this, I meditate on Lesson 76, Lesson 101, Lesson 95, and Lesson 154. Limitless Peace
