"Causa est" in this sentence

Question

How would I translate this sentence to make sense of the "causa est?" I feel that part of it might have to do with the best choice of word for "dicit" as well.

Divinitas enim in prima notione & concepto suo, dicit eminentiam & excellentiam in omni genere perfectionis, quae omnium rerum, ipsiusque creature rationalis, sive hominis causa est. Creatura vero rationalis, dicit intrinsece dependentiam a causa ista, secundum se totam, & totum sui, & capacitatem, sive idoneitatem ad religionem exercendam.

Answer 1

The est is the verb of the relative clause started by quae; it's used as a copula, and causa is the predicate nominative (complement). All the genitives – omnium rerum, ipsiusque creature (= creaturae) rationalis, and hominis – depend on causa.

...which is the cause of all things, and of the rational creature itself (or humankind).

I would translate dicit here as 'means' or 'signifies.'

Divinity means eminence and excellence...
