Some, from that verse of Peter, “Your adversary the Devil, &c.” [1 Pet 5:8] will have the Saviour’s command to be, that we should be merciful to the Devil, not causing him to endure punishment for our sakes. For as he puts in our way the incentives to vice, if we yield to his suggestions, he will be tormented for our sakes.
Some follow a more forced interpretation, that in baptism we have each of us made a compact with the Devil by renouncing him. If we observe this compact, then we are agreeing with our adversary, and shall not be cast into prison.
