Why did the people of the Middle Ages consider it necessary to divide society into estates?

In medieval society, a certain type of activity was assigned to each class. Everyone knew in what class he was born and, therefore, what kind of work he should do. It was believed that God himself singled out the estates and determined the place of each of them in society. The estate system consolidated the social, property and legal inequality of people.
