10. Warrant is given here likewise for censuring and restraining the rash individuals who assert that men should not be terrified by the Law, nor surrendered to Satan. No! it is our duty to teach men to purge out the old leaven; we must tell them they are not Christians, but devoid of the faith, when they yield to the wantonness of the flesh and wilfully persevere in sin against the warning of conscience. We should teach that such sins are so much the more vicious and damnable when practiced under the name of the Gospel, under cover of Christian liberty; for that is despising and blaspheming the name of Christ and the Gospel: and therefore such conduct must be positively renounced and purged out, as irreconcilable with faith and a good conscience. "Purge out the old leaven, that ye may be a new lump, even as ye are unleavened." 11. If we are to be a new, sweet lump, Paul says, we must purge out the old leaven. For, as stated, a nature renewed by faith and Christianity will not admit of our living as we did when devoid of faith and in sin, under the influence of an evil conscience. We cannot consistently be "a new lump" and partake of the Passover, and at the same time permit the old leaven to remain: for if the latter be not purged out, the whole lump will be leavened and corrupted; our previous sinful nature will again have supremacy and overthrow the faith, the holiness upon which we have entered and a good conscience. 12. Paul does not here speak of leaven in general; he commands to purge out the "old leaven," implying there may be good leaven. Doubtless he is influenced by respect for the words of the Lord Christ where (Mt 13, 33) he likens the kingdom of heaven also to leaven. In this latter case leaven cannot be bad in quality; rather, the object in mixing it with the lump is to produce good, new bread. Reference is to the Word of God, or the preaching of the Gospel, whereby we are incorporated into the kingdom of Christ, or the Christian Church. Though the Gospel appears to be mean, is despicable and objectionable to the world, yet such is its power that wherever introduced it spreads, finding disciples in whom it works; it transforms them, giving to them its own properties, even as leaven imparts its powers to the dough and causes it to rise. But Paul refers here to old, inactive and worthless leaven. He means teachings, views, or manner of life resulting from the Old Adam, from flesh and blood, and destructive of the pure, new doctrine, or a nature renewed by Christianity. Later on he terms it the "leaven of malice and wickedness," and in the verse under consideration bids the Corinthians be a new, pure lump.
