Believing…By Faith?

/

While talking to an acquaintance yesterday about a thorny Christological question, I made the statement that Christ was 100% God and 100% human. Pretty standard stuff. My acquaintance agreed, stating that he also believed this to be true, adding the caveat, “by faith.” I apparently looked confused when he used that phrase, because he persisted: “Wouldn’t you say that too?” he asked, “That you believe by faith?”

My answer surprised him, “No,” I said; “To say that would be either redundant or circular.” To believe is by definition to exercise faith, so to say that I “believe a thing by faith” is either (1) to repeat myself or (2) to beg the question (i.e., “I believe because I believe”). Instead, I explained, it would be more accurate to say that I believe a thing (e.g., the orthodox statement of Christ’s theanthropic person) because the Bible teaches it. IOW, the warrant for my faith is revelation.

As the conversation progressed, it became apparent that my acquaintance was using the phrase by faith incorrectly—and rather ominously so. What he meant by the phrase by faith is that faith acts as its own warrant. So, for instance, we believe some facts on the basis of sensory evidence; other facts we believe on the basis of logic; and still others we believe (despite the absence of sensory evidence or logical explanation) on the basis of “faith.” This understanding, I would contend, is none other than fideism (a.k.a. irrationalism): the idea that the Christian religion rests on assertions that have no warrant other than existential factors or, worse, personal opinion.

When we look at the several dozen biblical uses of the phrase by faith, we discover two possible meanings, but, notably, never the meaning described in the previous paragraph:

  • The phrase by faith can carry instrumental force. This idea is reflected most frequently in contexts of justification: we are saved “by grace and through faith” (Eph 2:8) and we are “justified by faith apart from observing the law” (so also Rom 4:13; 5:2; 9:30; Gal 2:16; Phil 3:9; etc.). By using the phrase this way we are communicating that Christians are not justified by the instrumentality of legal obedience, but by the instrumentality of trust in Christ.
  • The phrase by faith can also carry causal force. This idea is reflected most frequently in contexts of sanctification. For instance, when the author of Hebrews prefaces the many righteous deeds of the OT saints cataloged in Hebrews 11 with the phrase by faith, he means that Abel and Noah and Abraham obeyed because they believed God. Thus, when we read, “By faith Noah built an ark,” it means, “Because Noah believed God, he built an ark”; likewise, when we read “By faith Abraham offered up his son Isaac,” it means, “Because Abraham believed God, he offered up his son Isaac” (so also 2 Cor 5:7; 1 Thess 1:3; 2 Thess 1:11; etc.). The idea of warrant is present here, but never a blind warrant. Rather, the warrant in view is divine revelation.

Now, to be sure, there are some NT texts in which debate persists over which of these two meanings is in view (e.g., Rom 1:17; Heb 10:38), but what is important for this little statement is that there is no third option. There is no text that teaches Christians to “believe by faith.” Those who use such language are making an error. It may be a linguistic error of minor consequence or it may be a theological error of greater consequence. In either case, however, it is an error.

      No, this still is a redundancy or expression of fideism. Faith and belief are synonyms. Faith is not the substantive warrant or evidence for believing–it IS believing. Again, the correct thing to say is that I believe BECAUSE GOD SAID IT. This correctly identifies the warrant for faith.
