According to my own theory it only differentiates itself from time at a somewhat developed stage of the abstractive process.

The more usual way of expressing the relational theory of space would be to consider space as an abstraction from the relations between material objects.
Suppose now we assume absolute time and absolute space.

What bearing has this assumption on the concept of nature as bifurcated into causal nature and apparent nature?
Undoubtedly the separation between the two natures is now greatly mitigated.

We can provide them with two systems of relations in common; for both natures can be presumed to occupy the same space and the same time.

The theory now is this: Causal events occupy certain periods of the absolute time and occupy certain positions of the absolute space.
