287. The literal sense of the Ten Commandments contains general instructions on doctrine and life; but their spiritual and celestial senses contain universal instructions.
It is well known that the Ten Commandments are called in the Word the Law par excellence, because they contain everything concerning doctrine and life, not only everything which concerns God, but also everything which concerns man. That is why the law was written on two tablets, one dealing with God, the other with man. It is also well known that the whole of doctrine and life relate to love to God and love towards the neighbour. The whole of these loves is contained in the Ten Commandments. This is the teaching of the whole Word, as is evident from these words of the Lord:
Jesus said, You are to love the Lord your God with all your heart, and with all your soul and with all your mind, and your neighbour as yourself. The law and the prophets depend upon these two commandments. Matt. 22:35-37, 40.
The law and the prophets mean the whole Word. And further:
A lawyer testing Jesus said, Master, what must I do to inherit everlasting life? And Jesus said to him, What is written in the law? What is your reading of it? And he in answer said, You are to love the Lord your God with all your heart, and with all your soul and with all your strength and with all your mind, and your neighbour as yourself. And Jesus said, Do this, and you will live, Luke 10:25-28.
[2] Now since love to God and love towards the neighbour are the whole of the Word; and since the first tablet of the Ten Commandments contains in summary form the whole of love to God, and the second tablet contains the whole of love towards the neighbour, it follows that they contain the whole of doctrine and life. A look at the two tablets makes it plain that they are so linked that God from His tablet has man in view, and man in his turn from his has God in view. Thus there is a reciprocal viewing, such that on God's part He never fails to keep man in view and perform the actions needed for his salvation; and if a person accepts and does the things laid down in his tablet, the link becomes reciprocal. Then, as the Lord's words promised to the lawyer, 'Do this, and you will live.'
