John Calvin on 1 Corinthians 13:2

That faith, of which he speaks, is special, as is evident from the clause that is immediately added — so that I remove mountains Hence the Sophists accomplish nothing, when they pervert this passage for the purpose of detracting from the excellence of faith. As, therefore, the term faith is (πολύσημον) used in a variety of senses, it is the part of the prudent reader to observe in what signification it is taken. Paul, however, as I have already stated, is his own interpreter, by restricting faith, here, to miracles. It is what Chrysostom calls the “faith of miracles,” and what we term a “special faith,” because it does not apprehend a whole Christ, but simply his power in working miracles; and hence it may sometimes exist in a man without the Spirit of sanctification, as it did in Judas. The reader will observe, that this is, in substance, what has been stated by Calvin previously, when commenting on 1 Corinthians 12:10. — Ed.
