Why, it is consonant with Romans 13. Insofar as the current US government protects justice as expressed in the Ten Commandments and similar precepts of moral theology, and is not a "terror to good works" it is legitimate. When the US government becomes "terror to good works" as for example, when it prohibits expression of religion or, most grievously, allows for the killing of the unborn or the infirm, then that governmental activity is not to be obeyed or facilitated and is illegitimate.

The US government is not consonant with Romans 13. It does not protect justice as expressed in the Ten Commandments, it is not consistent with similar precepts of moral theology and increasingly so, is a terror to good works.
Now give us your judgement.
