Everything in the universe is an interconnected whole. In the world of life, the survival and development of one kind of life must depend on the existence of many other kinds of life. In human society, a person's survival and development must depend on the existence of many other people. Therefore, it is the diversity of species that constitutes the colorful living environment of human beings. It is the endless life and creation of all kinds of people that constitute the ever-changing social environment on which each of us depends for survival and development. Therefore, to love all life is to love the living environment of human beings. To love all people is to love our own living environment. Maintaining the relative stability of species diversity in the life world is to protect the future of human development. Safeguarding everyone's right to survive and live is to maintain the relative stability of society, thus ensuring a good social environment for each of us to survive and live. Therefore, the universal love advocated by Jesus Christ, though sometimes neglected, is of eternal value to the development of human society and even the wider life world.
Second, "fraternity" is the theoretical destination of the theory of original sin.
Adam and Eve, the ancestors of mankind, stole the forbidden fruit from the Garden of Eden, so they were born with original sin. The theoretical purpose of the theory of original sin is to make people love all life and all people with the universal mood of atonement. Therefore, the original sin theory in Christianity, like the reincarnation theory in Buddhism, is to warn or induce people to abandon evil deeds and care for life. Therefore, in this sense, the theory of original sin is also a "power law". Therefore, only "fraternity" is the fundamental doctrine of Jesus Christ.
Third, overcoming the negative influence of the original sin theory can really make people move towards fraternity.
The theory of original sin can make people feel guilty about everything in the world, thus eventually leading people to fraternity. This is the positive influence of the original sin theory and the real value it wants to achieve. However, the theory of original sin may also cause people to have negative thoughts such as "guilty anyway, it doesn't matter how much", and even do things that violate the principle of "fraternity" more brazenly. This is of course the gloomy psychology of some believers, but it is undoubtedly an objective reality. As a Christian who does not love or even do evil, there is such a misinterpretation of "original sin" in his heart. Therefore, in order to implement the fraternity advocated by Jesus Christ, we must seriously understand the true meaning of the theory of original sin and completely eliminate its negative influence.
Doctrine is only a belief of human beings and belongs to a part of spiritual culture. Didn't say which is the best and which is the latest, just like radish and cabbage have their own love. Can you say that Buddhism is not good? It's just that Buddhism is in the East and Christianity is in the West.
