The third section was intended to be strict with members of the Confederacy who fought against the United States. It required a two-thirds vote of Congress to allow leaders of the Confederacy to regain their citizenship or hold office. To be allowed to hold a federal office, former confederates had to swear an oath to uphold the constitution. Section four said the federal government would not repay Confederate debts. Section five means what it says, Congress will enforce the provisions of the 14th amendment.
