Division of Natural Law
648. What do you think of the division of natural law into ten parts, the laws of adoration, labor, reproduction, preservation, destruction, society, progress, equality, liberty, and the law of justice, love, and charity?
“The division of God’s law into ten parts comes from Moses and covers all the circumstances of life, which is the essential point. You may adopt it, without it being unconditional, just like any of the other various classification systems which depend on the perspective or situation in question. The last law is the most important because it includes all the others. By observing this law, humankind can advance the most quickly in spiritual life.”
