THE GREATEST OF THE COMMANDMENTS
4. But when the Pharisees had heard that He had put the Sadducees to silence, they were gathered together. Then one of them, which was a lawyer, asked Him a question, tempting Him, and saying, Master, which is the greatest commandment in the law? Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind. This is the first and great commandment. The second is like unto it, thou shalt love thy neighbour as thyself. On these two commandments hang all the law and the prophets (Matthew, 22: 34-40).
5. Charity and humility, such is the only path to salvation. Selfishness and pride are the paths to ruin. This principle is found to be formulated on the following precise terms: "Love your God with all your soul and your neighbour as yourself; all the law and the prophets are contained in these two commandments." And so there would be no mistake in the understanding of the meaning of the love for God and for our neighbour, He then added: "And there is the second commandment, which is similar to the first." This means that it is not possible to truly love God without loving your neighbour, nor to love your neighbour without loving God. Straightaway, all that you do against your neighbour you also do against God. Therefore, as it is not possible to love God without practising charity towards one's neighbour. All of mankind's obligations are resumed in the maxim: without charity there is no salvation.
