How very necessary it is, he has declared not only by words but also by examples. When he was pleased to shed the light of his truth in greater effulgence on Cornelius, he sent an angel from heaven to despatch Peter to him (Acts 10:3). When he was pleased to call Paul to the knowledge of himself, and ingraft him into the Church, he does not address him with his own voice, but sends him to a man from whom he may both obtain the doctrine of salvation and the sanctification of baptism (Acts 9:6-20). If it was not by mere accident that the angel, who is the interpreter of God, abstains from declaring the will of God, and orders a man to be called to declare it; that Christ, the only Master of believers, commits Paul to the teaching of a man, that Paul whom he had determined to carry into the third heaven, and honour with a wondrous revelation of things that could not be spoken (2 Cor. 12:2), who will presume to despise or disregard as superfluous that ministry, whose utility God has been pleased to attest by such evidence?
Analysis: For Calvin, teachers are given as "a special benefit on men." He emphasizes, in particular, their duty of preaching. The "governing and keeping" of the church is "through ministers." These are men especially called to declare the gospel.
