Explanation:

The United States is characterized by granting great powers to its president, but the constitution also consecrates the separation of powers and respects a wide autonomy to the territories that comprise it. In short, in political jargon, "brakes and counterweights" to make effective the separation of powers. The powers are separated in the executive, judicial and legislative branches. In the examples given, we can say that the church is not part of any of the powers of the state, therefore it cannot intervene in any of them.
