An excerpt from a blog post on the Society of St.Pius X website titled Pope Francis and Modernism.
SSPX write (emphasis added):
How harmonious it would have sounded to Catholic ears worldwide if Scalfari had been given a rational proof for God’s existence! It could have been done very briefly:
Dear Doctor, we know from our uniform experience that everything around us is finite and limited. But what is finite and relative cannot be explained without the infinite and absolute. It is impossible that there be caused causes without an Uncaused One, received being without Unreceived Being, participated goodness without Absolute Goodness. Therefore, we must admit these absolutes — to which everyone gives the name ‘God’ — so as not to fall into irrationality.”
