The first and foremost merit of Protestant Reformation is that it dispensed with one, unique, and unquestionable authority, embodied in the Roman Catholic Church. It opened the path to pluralism - a multitude of opinions that seek to be freely expressed, without censure and fear of punishment. It dismantled the dogma of one truth and one truth only - whether it be about God, Trinity, priests, an attitude towards worldly riches or anything else. Even though it was not secular, its focus on living in this world rather than in anticipation of heaven or hell, opened new perspectives for the development of secularism too.

This also meant having more labor resources, more hands ready to work in the farm fields to grow more crops, to produce more food for the empíre and trading purposes. Better crops and food production meant more trade, and more trade translated into more income and resources for the empire.
