John 15:3 - Matthew Poole's English Annotations on the Holy Bible

Now that the traitor is gone out from you, ye are all clean; not by any works which you do, much less upon the account of any legal and ceremonial rites and purifyings; but through my word, your believing and obeying, Ephesians 5:26 1 Peter 1:22. Our cleansing is in holy writ attributed sometimes to the blood of Christ, sometimes to the Spirit, sometimes to the word. By the blood of Christ we are made clean as to justification, washed; but yet we had need wash our feet, contracting soil every day in a sinful world, from which we are cleansed by the purifying virtue of the Holy Spirit, working by and together with the word, which purgeth us of our dross, and maketh us obedient to the will of God.
