Is the equal dignity of all men (homines) founded in nature or in grace? Both. Matter is the principle of individuation and the highest operations of the intellect do not occur through a material organ. The capacity of the intellect to make use of man’s lower faculties, such as the imagination, may be impeded by the imperfect subjection of the body’s matter to its form (the soul) which results from the loss of the preternatural gifts but this privation (a consequence of the Fall) afflicts all men. Moral (and therefore political) questions appertain to the will and intellect as such and thus there can be no pretext for the founding of civil rights and their variation upon supposed biological variation between ‘races’. Any attempt to do so is pagan and materialist.’ Sexism and Racism are false de jure and de facto. Imagine an orchestra of identical musicians with differing instruments. In bodily terms the musicians are identical but they have only ever played, studied and practiced with the individual instrument they play in the orchestra. Their habits and the development of their bodies are entirely framed by the instrument they have grown up with. Nevertheless, each is possessed of the same theoretical capacity and with a perfect instrument and ideal training  unlimited potential. In this fallen world no one is possessed of a perfect instrument and ideal training but it will not always be thus. In fact, in the order of grace everyone is possessed of a perfect instrument and ideal training for “to them that love God, all things work together unto good”. In an unfallen world the equality of all men would be an absolute. In this world (and all possible worlds) it is essentially preserved. Under grace this essential equality is transformed into differing eternal rewards determined by charity. “In the Evening of Life, We will be Judged on Love Alone.” Of course when God crowns our merits He crowns His own gifts but though founded upon grace and the principle of predilection that judgement is not unjust. God’s grace does not conflict with the freedom of man. When we have run the race to the finish it is the equality of our starting place that displays the justice of God. That starting place is nature.
