The visionary impulse giving rise to apocalyptic eschatology tends to be strongest among those embracing the prophetic promise of Yahweh's restoration of the faithful but at the same time witnessing the political and cultic structures of their nation falling into the hands of adversaries, thereby vitiating the possibility of fulfillment within the existing order of things. The pragmatic or realistic impulse tends to be strongest among those exercising control over political and religious structures; they often actively oppose the visionaries, viewing them as a threat to their position of leadership.
