Essentially, yes, of course. The foundation of paganism is the belief in God. But without any "scriptures." At best, there are traditions, which are modified from generation to generation.
And then – paganism is naturally organic to humans. Many, and very many, "Christians" completely misunderstand the essence of Christian dogmas and are, in essence, pagans, coming to church to "appease their souls" or "ask God" for something, i.e., almost always it is one of the "gods" that is closest to their perception (or the Virgin Mary). Few people turn to the One God directly to solve their problems. Everyone in Christianity has their own "god" (some saint, a righteous person, or the Virgin Mary). So the pagan essence "works" even in Christianity because humanity has not come up with anything better than this essence.
