Commentary on the Gospel According to John John Calvin (continued)
Commentary on John here we are reminded how widely his judgment differs from ours; for he sees clearly those things which we cannot perceive, because they are concealed by some disguise; and he estimates according to their hidden source, that is, according to the most secret feeling of the heart, those things which dazzle our eyes by false luster. This is what Solomon says, that
God weighs in his balance the hearts of men, while they flatter themselves in their ways, (Proverbs 21:2.)
Let us remember, therefore, that none are the true disciples of Christ but those whom He approves, because in such a matter He alone is competent to decide and to judge.
A question now arises: when the Evangelist says that Christ knew them all, does he mean those only of whom he had lately spoken, or does the expression refer to the whole human race? Some extend it to the universal nature of man, and think that the whole world is here condemned for wicked and perfidious hypocrisy. And, certainly, it is a true statement, that Christ can find in men no reason why he should deign to place them in the number of his followers; but I do not see that this agrees with the context, and therefore I limit it to those who had been formerly mentioned.
25. For he knew what was in man. As it might be doubted whence Christ obtained this knowledge, the Evangelist anticipates this question, and replies that Christ perceived every thing in men that is concealed from our view, so that he could on his own authority make a distinction among men. Christ, therefore, who knows the hearts, had no need of any one to inform him what sort of men they were. He knew them to have such a disposition and such feelings, that he justly regarded them as persons who did not belong to him.
The question put by some — whether we too are authorized by the example of Christ to hold those persons as suspected who have not given us proof of their sincerity — has nothing to do with the present passage. There is a wide difference between him and us; for Christ knew the very roots of the trees, but, except from the fruits which appear outwardly, we cannot discover what is the nature of any one tree. Besides, as Paul tells us, that charity is not suspicious, (1 Corinthians 13:5,) we have no right to entertain unfavorable suspicions about men who are unknown to us. But, that we may not always be deceived by hypocrites, and that the Church may not be too much exposed to their wicked impostures, it belongs to Christ to impart to us the Spirit of discretion.
