Question

Which quality of the Roman Catholic Church does the archetype of the mother illustrate in this line from the passage?

And that this Romane church is mother and mistres of all churches; and (by the Lord's ordinance) hath principality of ordenary power aboue all others, as being the mother and mistres of all Christian belieuers.
its nurturing, protective nature
its primacy over other forms of worship
its great power based on material riches
its appeal to a broad range of people

Answer 1

I think that the most relevant part is this one:

"hath principality of ordenary power aboue all others," - this means that the Roman church is more importnat, above the others.

So the correct answer would be
its primacy over other forms of worship
