What is this principle? It is not embodied in some narrow doctrinaire formula, as some of our opponents would suggest. Still less is it a particular economic or political formula laid down once for all. It is essentially a moral principle on which we believe the life of nations and of individuals should be ordered. That principle is the brotherhood of man.

the basic spiritual truth that men are brothers in the sight of God

A mystic bond of brotherhood makes all men one.

When the Prophet says "brother", we should interpret this as universal brotherhood, which includes Muslims and non-Muslims.

There is a fraternity more comprehensive and more universal than the “brotherhood of man.” Let us think and speak of the “brotherhood of being.” Let us see in the ox a patient, industrious kinsman, worthy of respect. Let us see and recognize in the sheep a meek and docile fellow creature appealing to us for protection and admiration.

The principle of the brotherhood of man is that narcissistic one, for the grounds for that love have always been the assumption that we ought to realize that we are the same the whole world over.

The Pope has placed before us a beautiful goal, this universal brotherhood, which logically, includes women and men, for Saint Francis did not exclude anyone! It is a commitment that begins to daily life, in the relationships that each of us have, and then extends it to the areas of professional or social commitment where we find ourselves, at whatever level. Logically, in the current situation, this is not easy, we cannot hide it and be naïve, but we have a goal and a great hope, for which we are also responsible. Moreover, I have faith that if we try to do our small part, God will do the rest if we let Him.

It is our suffering that brings us together. It is not love. Love does not obey the mind, and turns to hate when forced. The bond that binds us is beyond choice. We are brothers. We are brothers in what we share. In pain, which each of us must suffer alone, in hunger, in poverty, in hope, we know our brotherhood. We know it, because we have had to learn it. We know that there is no help for us but from one another, that no hand will save us if we do not reach out our hand. And the hand that you reach out is empty, as mine is. You have nothing. You possess nothing. You own nothing. You are free. All you have is what you are, and what you give.

The universal brotherhood of man is our most precious possession, what there is of it.

We are brothers in what we share. In pain, which each of us must suffer alone, in hunger, in poverty, in hope, we know our brotherhood. We know it, because we have been forced to learn it.

The idea of brotherhood redawns upon the world with a broader significance than the narrow association of members in a sect or creed; and thinkers of great soul like Lessing challenge the world to say which is more godlike, the hatred and tooth-and-nail grapple of conflicting religions, or sweet accord and mutual helpfulness. Ancient prejudice of man against his brother-man wavers and retreats before the radiance of a more generous sentiment, which will not sacrifice men to forms, or rob them of the comfort and strength they find in their own beliefs. The heresy of one age becomes the orthodoxy of the next. Mere tolerance has given place to a sentiment of brotherhood between sincere men of all denominations.

We all know that the Bible upholds slavery in its very worst and most cruel form; and how it can be said that a religion founded upon a Bible that upholds the institution of slavery has taught and established the fact of human brotherhood, is beyond my imagination to conceive.

Weak or strong, clever or simple, we are all brothers.

All the human kind is but one family, dispersed over the face of the whole earth; all men are brothers, and ought to love each other as such.
