Jesus, not Faith, is the Christian's Righteousness

Theodore Beza, a disciple of John Calvin, points out that the faith alone that saves, is not simply, faith as a vague energy, but faith in Jesus alone: 

"Here is the explanation of our justification by faith alone: faith is the instrument which receives Jesus Christ and, consequently, which receives His righteousness, that is to say, all perfection...we do not say that faith is a virtue which makes us righteous, in ourselves, before God.  For this would be to put faith in the place of Jesus Christ who is, alone, our perfect and entire righteousness...

It is established that to be assured of one's salvation, through faith, is not only neither presumption nor arrogance, but, on the contrary, is the sole means of stripping oneself of all pride, to give all glory to God...Because faith alone teaches us to go out of ourselves, and compels us, to earnestly acknowledge that in ourselves there is nothing but cause for complete damnation.  Thus it sends us away to Jesus Christ, and it teaches us and assures us that we shall find salvation before God through His righteousness alone.  Truly, all that is in Jesus Christ, that is to say, all the righteousness and perfection (in Him there was no sin and moreover He has fulfilled all the righteousness of the Law), is placed to our account and gifted to us as if it were our own, provided that we embrace Him by faith."  (Source).
