The nineteenth century’s embrace of the new concept of romantic nationalism offered a purpose without Judeo-Christian values or Greek telos: the nation, spurring forward the progress of history, unified by ethnicity and background, proselytizing with its power. Nationalism also unified the question of individual and collective capacity by suggesting that they were one and the same: your individual identity lay in your identity as a member of the collective. And the collective existed to give you spirit and strength and purpose.
It seems that Nationalism in the 21st century United States is also drifting from Biblical principles, in favor of political efficiency.
