John Calvin, on the 2 Voices of Every Pastor

“A pastor has two voices, one for gathering the sheep and the other for driving away wolves and thieves. The Scripture supplies him with the means for doing both, and he who has been rightly instructed in it will be able both to rule those who are teachable and to refute the enemies of the truth. Paul notes this double use of the Scripture when he says that he should be able both to exhort and to convict the gainsayers.”
