Constantine, Pagan Rome, the Pagan Papacy and the Reformation are very relevant to this discussion of Dualism and its effects.

The Sacred/Secular Divide that then becomes the Grace/Nature Divide with Thomas Aquinas now become The Clergy/Laity Divide not just with the Pagan Roman Catholic 'Church' but overspills into Protestant Evangelical church culture as well.

Despite the comprehensive impact that the Reformation had on Western Culture, tragically it perpetuated this divide between what is now the Clergy/Laity Divide.

When it is properly unpacked the Sacred/Secular Divide rooted in Plato Dualism is reveals how Gnostic it is. Gnosis means 'knowledge' but it is secret knowledge. Gnosticism rejects creation and all things physical. Yet so does the Sacred/Secular Divide marked by a professionalised 'Clergy' and passive dependent Laity (people);

The huge cultural vaccum that was filled by the Rationalism of the Enlightenment, descending into the 'Death of God' school meant that 'man became the measure of all things'.

This is why Western culture has now travelled full circle and has returned to its Greco-Roman paganism.

Christ came into an Ancient Pagan culture, transformed it, but the Dualism that keeps people passive, has meant that the 'ancient gods have risen again'. Today's Neo (new) Paganism has resulted from a REJECTION of the Gospel. This is where we are at. Neo Paganism, Statism, Totalitarianism, Technocracy.....the eschaton of man deified.
