And he gave the apostles, the prophets, the evangelists, the shepherds and teachers, to equip the saints for the work of ministry, for building up the body of Christ, until we all attain to the unity of the faith and of the knowledge of the Son of God, to mature manhood, to the measure of the stature of the fullness of Christ, so that we may no longer be children, tossed to and fro by the waves and carried about by every wind of doctrine, by human cunning, by craftiness in deceitful schemes.

Ephesians 4:11-14 ESV

This passage of Scripture came to mind today, and I thought it might be interesting to read Calvin’s teaching on these verses. From his commentary on Ephesians:

Tossed to and fro, and carried about. The distressing hesitation of those who do not place absolute reliance on the word of the Lord, is illustrated by two striking metaphors. The first is taken from small ships, exposed to the fury of the billows in the open sea, holding no fixed course, guided neither by skill nor design, but hurried along by the violence of the tempest.

The next is taken from straws, or other light substances, which are carried hither and thither as the wind drives them, and often in opposite directions. Such must be the changeable and unsteady character of all who do not rest on the foundation of God’s eternal truth. It is their just punishment for looking, not to God, but to men. Paul declares, on the other hand, that faith, which rests on the word of God, stands unshaken against all the attacks of Satan.

By every wind of doctrine. By a beautiful metaphor, all the doctrines of men, by which we are drawn away from the simplicity of the gospel, are called winds God gave us his word, by which we might have placed ourselves beyond the possibility of being moved; but, giving way to the contrivances of men, we are carried about in all directions.

By the cunning of men. There will always be impostors, who make insidious attacks upon our faith; but, if we are fortified by the truth of God, their efforts will be unavailing. Both parts of this statement deserve our careful attention. When new sects, or wicked tenets, spring up, many persons become alarmed. But the attempts of Satan to darken, by his falsehoods, the pure doctrine of Christ, are at no time interrupted; and it is the will of God that these struggles should be the trial of our faith. When we are informed, on the other hand, that the best and readiest defense against every kind of error is to bring forward that doctrine which we have learned from Christ and his apostles, this surely is no ordinary consolation. …

Let us therefore confidently expect that we shall reap the advantage which is here promised, — that all the impostures of men will do us no harm. They will attack us, indeed, but they will not prevail. We are entitled, I acknowledge, to look for the dispensation of sound doctrine from the church, for God has committed it to her charge … .
