The Protestant term “by faith alone” is one that separates orthodox Protestantism from not only every other world religion outside of Christianity, but also from certain segments of Christianity. Strictly speaking, Protestants believe that human justification before a Holy God is by faith “alone”, apart from human works of any sort.
Those who would add human works to faith sometimes use the argument that the word “alone” does not appear alongside “faith”, and therefore gives license to add imperfect human works to the perfect, finished work of Christ. Not only does adding that which is imperfect to that which is perfect sound a bit incongruous, it also falls a bit short in the sound logic department.
The argument from silence (also called argumentum ex silentio in Latin) is generally a conclusion based on silence or lack of contrary evidence. [i] In the field of classical studies, it often refers to the deduction from the lack of references to a subject in the available writings of an author to the conclusion that he was ignorant of it.[ii] When used as a logical proof in pure reasoning, the argument is classed among the fallacies, but an argument from silence can be a convincing form of abductive reasoning, a form of reasoning that allows one to insert a desired meaning into a certain text.
There are a couple of problems with that form of reasoning when it comes to the matter of man’s justification before a Holy God:
First, there are many things taught in Scripture that are not explicitly stated: common examples are the words “Trinity” and “monotheism” which are nowhere stated in Scripture. To argue that the absence of the specific term “faith alone” means that human works can be added to faith for justification, when the context of scripture (both OT and NT) clearly teaches otherwise, is pure nonsense.
Justification by faith alone is derived from the fact that 1) Scripture teaches that salvation is by simple faith or trust in Christ and 2) that Scripture absolutely affirms salvation cannot be by works. Therefore, if salvation is by simple faith, and cannot be by works, the phrase, “Salvation is by grace through faith alone,” cannot be considered anti-scriptural but a true presentation of what the Bible teaches.
Hear the familiar words of the Apostle Paul:
“For we hold that one is justified by faith apart from works of the law.” – Rom 3:28
“For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast.” – Eph 2:8-9
“But if it is by grace, it is no longer on the basis of works; otherwise grace would no longer be grace.” – Rom 11:6
These are not remote, isolated passages of scripture. They reflect the entire body of Paul’s teaching, to both Jews and Gentiles. Furthermore,the often used argument in the face of such clarity of the text, that Paul was only speaking of the Moasic law in passages such as Rom 3:28, is as as fallacious as arguing from silence.
