In your example, there are no such phrases as “make Of” or “made of.” What do you expect with “make Of”? Of all nations, what is perfectly nested and unremarkable about this prepositional phrase? In North American dialect, “from all nations ” or “out of all nations” are close synonyms. What

does the phrase “Disciples of all nations” mean in English? This is a noun phrase in which the leading noun is changed by the prepositional phrase. Who was making this complete noun sentence about? Another option is to consider “disciples” as the direct object and “of all nations” as the object complement. I

prefer the object complement option. I see the same structure in “make disciples of all nations” as I do in “name the dog Spot” and “Get him ready.” All these imperatives are transitive and causative. The complements relate to their direct objects as a result of the action of their verbs. As

a result, ‘of all nations’ is a coherent prepositional phrase which, one way or another, modifies “disciples”. It contains the preposition “of” and the object “all nations”.
