This article (as I have said) I cannot relate better than to Sanctification, that through the same the Holy Ghost, with His office, is declared and depicted, namely, that He makes holy. Therefore we must take our stand upon the word Holy Ghost, because it is so precise and comprehensive that we cannot find another. For there are, besides, many kinds of spirits mentioned in the Holy Scriptures, as, the spirit of man, heavenly spirits, and evil spirits. But the Spirit of God alone is called Holy Ghost, that is, He who has sanctified and still sanctifies us. For as the Father is called Creator, the Son Redeemer, so the Holy Ghost, from His work, must be called Sanctifier, or One that makes holy. But how is such sanctifying done? Answer: Just as the Son obtains dominion, whereby He wins us, through His birth, death, resurrection, etc., so also the Holy Ghost effects our sanctification by the following parts, namely, by the communion of saints or the Christian Church, the forgiveness of sins, the resurrection of the body, and the life everlasting; that is, He first leads us into His holy congregation, and places us in the bosom of the Church, whereby He preaches to us and brings us to Christ. For neither you nor I could ever know anything of Christ, or believe on Him, and obtain Him for our Lord, unless it were offered to us and granted to our hearts by the Holy Ghost through the preaching of the Gospel. The work is done and accomplished; for Christ has acquired and gained the treasure for us by His suffering, death, resurrection, etc. But if the work remained concealed so that no one knew of it, then it would be in vain and lost. That this treasure, therefore, might not lie buried, but be appropriated and enjoyed, God has caused the Word to go forth and be proclaimed, in which He gives the Holy Ghost to bring this treasure home and appropriate it to us. Therefore sanctifying is nothing else than bringing us to Christ to receive this good, to which we could not attain of ourselves. Learn, then, to understand this article most clearly. If you are asked: What do you mean by the words: I believe in the Holy Ghost? you can answer: I believe that the Holy Ghost makes me holy, as His name implies. But whereby does He accomplish this, or what are His method and means to this end? Answer: By the Christian Church, the forgiveness of sins, the resurrection of the body, and the life everlasting. For, in the first place, He has a peculiar congregation in the world, which is the mother that begets and bears every Christian through the Word of God, which He reveals and preaches, [and through which] He illumines and enkindles hearts, that they understand, accept it, cling to it, and persevere in it.
