The President (aka Executive Branch) is responsible for implementing legislation and executive orders. The US Constitution gives the president this power, as Article Two outlines the expectations and rights of the executive branch. This power given to the president can be checked by other branches of the federal government though, as the Supreme Court has the power of judicial review. This means the Supreme Court can rule acts of legislation or executive orders as unconstitutional.
The federalist papers were intended to convince the colonists and the states to ratify the constitution, since the Federalists believed that a stronger federal government would be better.
Judaism and Cristianity spread around the world because Jews where kicked out of their countries to other parts of the world, and Christianity spread because of the work of their missionaries.
