Why Freemasons believe in God? The absence of God removes from the universe and from humanity its moral foundation. If all that exist is only "matter", (the original and permanent substance of all reality), we can live just as any other animal.
Evil voices say "Let the poor die, let's make all the populations of poor countries disappear, so we will have more water, more crude oil, more sustainability conditions for the world because we would be reducing the number of our biggest predator, namely man himself."
Only the notion of God as a moral being offers humanity the foundation of indiscriminate solidarity.
The ethical foundation of the universe and humanity rests on love, expression of the Great Architect of the Universe, The Divine Being that gives birth to everything! This necessarily implies the realization that the correlation that binds man to mankind is connected to the understanding of a higher correlation which binds man to God and God to man.
Since it is only on the relationship with our neighbor that we are complete, and only God offers the foundation for the unity of humanity, every denial of love, which is equivalent to the alienation of the other, is also equivalent to the disintegration of ourselves.
