Peter, an apostle of Jesus Christ, to the chosen ones who are living as strangers in the Dispersion in Pontus, Galatia, Cappadocia, Asia, and Bithynia,
Unto obedience He adds two things to sanctification, and seems to understand newness of life by obedience, and by the sprinkling of the blood of Christ the remission of sins. But if these be parts or effects of sanctification, then sanctification is to be taken here somewhat different from what it means when used by Paul, that is, more generally. God then sanctifies us by an effectual calling; and this is done when we are renewed to an obedience to his righteousness, and when we are sprinkled by the blood of Christ, and thus are cleansed from our sins. And there seems to be an implied allusion to the ancient rite of sprinkling used under the law. For as it was not then sufficient for the victim to be slain and the blood to be poured out, except the people were sprinkled; so now the blood of Christ which has been shed will avail us nothing, except our consciences are by it cleansed. There is then to be understood here a contrast, that, as formerly under the law the sprinkling of blood was made by the hand of the priest; so now the Holy Spirit sprinkles our souls with the blood of Christ for the expiation of our sins.
