How Do The Persons of the Trinity Relate?

“How do the Persons of the Trinity relate in their role and work? ‘There is union of all three persons in God’s works ad extra. Each person bears the whole divine nature. Whatever one person does, the other persons also play a role (creation, redemption).’ ‘Each works ‘in’ the other two, so that nothing happens without all three working together. But the involvement of each is distinct and appropriate.’”
