For these monks and their church that may not be the point, for medieval churches it very much was. God was not something that a small group of people in the church believed in, God was a fact to those living in those places at those times. You’re right that folks here have a different world view, but you can’t understand the cathedral without understanding the world view of those who built it.

And - “this building has no point whatsoever apart from how the monks see it” is true for everything and every viewpoint.
