Calvin: Acceptable Good Works Justified By Faith Alone

"I say that it is owing to free imputation that we are considered righteous before God; I say that from this also another benefit proceeds, viz., that our works have the name of righteousness, though they are far from having the reality of righteousness.  

"In short, I affirm, that not by our own merit but by faith alone, are both our persons and works justified; and that the justification of works depends on the justification of the person, as the effect on the cause. Therefore, it is necessary that the righteousness of faith alone so precede in order, and be so pre-eminent in degree, that nothing can go before it or obscure it."

John Calvin, Acts of the Council of Trent with the Antidote
