What we call Modernity has old roots. In most respects, it represents a secularisation of ideas and perspectives borrowed from Christian metaphysics, which spread into secular life following a rejection of any transcendent dimension.
Actually, one finds in Christianity the seeds of the great mutations that gave birth to the secular ideologies of the first post-revolutionary era.

• Individualism was already present in the notion of individual salvation and of an intimate and privileged relation between an individual and God that surpasses any relation on Earth.
• Egalitarianism is rooted in the idea that redemption is equally available to all mankind, since all are endowed with an individual soul whose absolute value is shared by all humanity.
• Progressivism is born of the idea that history has an absolute beginning and a necessary end, and that it unfolds globally according to a divine plan.
• Finally, universalism is the natural expression of a religion that claims to manifest a revealed truth which, valid for all men, summons them to conversion."
