Even in affirming this, nevertheless, the fathers did not say that the three persons were each doing the exact same thing. They were inseparably operating in every thing, but they were operating according to what is appropriate to each of the persons. So the Son can be doing what the Son sees the Father doing (affirming the monarchy of the Father and the inseparability of operations), while not literally doing the exact same activity--since they are two distinct persons of the Trinity. The persons have unique, yet inseparable operations in every action of the Trinity. The task the Trinity is doing is one, while the operations are not.
