Roman Catholicism takes a similar approach, only they call the nous the "soul". Christ is unclear on this IMO, but Paul makes the claim that that salvation is only through a truthful declaration (faith) that you believe Christ is your Lord. What "salvation is through" means is less clear, it's stated as a guarantee (at least in KJV) but it could also mean it's only the first step to unity with the Father. I do not believe salvation is obtained through the sacraments and good deeds, as this is works-only, but am of the belief (I Peter 2:9) that works and deeds are evidence of salvation and are not the means. Purification and an outpouring of holy spirit is obtained by quietly being present and one with the Father
