In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God; all things were made through him, and without him was not anything made that was made. In him was life, and the life was the light of men. The light shines in the darkness, and the darkness has not overcome it. There was a man sent from God, whose name was John. He came for testimony, to bear witness to the light, that all might believe through him. He was not the light, but came to bear witness to the light. The true light that enlightens every man was coming into the world. He was in the world, and the world was made through him, yet the world knew him not. He came to his own home, and his own people received him not. But to all who received him, who believed in his name, he gave power to become children of God; who were born, not of blood nor of the will of the flesh nor of the will of man, but of God. And the Word became flesh and dwelt among us, full of grace and truth; we have beheld his glory, glory as of the only Son from the Father [...]
Justification by faith and not by legal practices (Paul to Romans 3, 23-31) ...
Since all have sinned and fall short of the glory of God, they are justified by his grace as a gift, through the redemption which is in Christ Jesus, whom God put forward as an expiation by his blood, to be received by faith [...] Then what becomes of our boasting? It is excluded. On what principle? On the principle of works? No, but on the principle of faith. For we hold that a man is justified by faith apart from works of law [...]
... but, as says it James, if the faith did not produce not works of the Love, faith died (2,14-26)
What does it profit, my brethren, if a man says he has faith but has not works? Can his faith save him? If a brother or sister is ill-clad and in lack of daily food, and one of you says to them, "Go in peace, be warmed and filled," without giving them the things needed for the body, what does it profit? So faith by itself, if it has no works, is dead. [...] You believe that God is one; you do well. Even the demons believe -- and shudder. Do you want to be shown, you shallow man, that faith apart from works is barren? Was not Abraham our father justified by works, when he offered his son Isaac upon the altar? You see that faith was active along with his works, and faith was completed by works, and the scripture was fulfilled which says, "Abraham believed God, and it was reckoned to him as righteousness"; and he was called the friend of God. You see that a man is justified by works and not by faith alone. For as the body apart from the spirit is dead, so faith apart from works is dead".
