We now have to consider the persons as compared to one another: firstly, with regard to equality and likeness; secondly, with regard to mission. Concerning the first there are six points of inquiry.

(1) Whether there is equality among the divine persons?

(2) Whether the person who proceeds is equal to the one from Whom He proceeds in eternity?

(3) Whether there is any order among the divine persons?

(4) Whether the divine persons are equal in greatness?

(5) Whether the one divine person is in another?

(6) Whether they are equal in power?
