Can the Decalogue itself change a man into a dignified human being?

[Rutherford2]

The 10 commandments states the principles of moral life valid for every man. Therefore, if he follows the 10 commandments does he becomes a better and dignified human being? Are there extra duties, knowledge or laws that a man must attain or fulfill apart from the 10 commandments in order to become a dignified human?

A person can do good naturally without grace, but it will not be salvic without grace. We are not under the New Covenant so we should receive the sacraments.

Matthew 5:

17 Do not think that I have come to abolish the law or the prophets. I have come not to abolish but to fulfill. 18 Amen, I say to you, until heaven and earth pass away, not the smallest letter or the smallest part of a letter will pass from the law, until all things have taken place. 19 Therefore, whoever breaks one of the least of these commandments and teaches others to do so will be called least in the kingdom of heaven. But whoever obeys and teaches these commandments will be called greatest in the kingdom of heaven. 20 I tell you, unless your righteousness surpasses that of the scribes and Pharisees, you will not enter into the kingdom of heaven.

Matthew 23

“Teacher, which commandment in the law is the greatest?” 37 He said to him, “You shall love the Lord, your God, with all your heart, with all your soul, and with all your mind. 38 This is the greatest and the first commandment. 39 The second is like it: You shall love your neighbor as yourself. 40 The whole law and the prophets depend on these two commandments.”

John 13:

31 When he had left, Jesus said, “Now is the Son of Man glorified, and God is glorified in him. 32 If God is glorified in him, God will also glorify him in himself, and he will glorify him at once. 33 My children, I will be with you only a little while longer. You will look for me, and as I told the Jews, ‘Where I go you cannot come,’ so now I say it to you. 34 I give you a new commandment: love one another. As I have loved you, so you also should love one another. 35 This is how all will know that you are my disciples, if you have love for one another.”
