|1 Corinthians 1:2|
1 Unto the church of God that is at Corinth, to those set apart by Christ Jesus, called to be saints, with all who in every place call upon the name of Jesus Christ our Lord, themselves and us. This verse has typically been translated as "to those who are sanctified in Christ Jesus," instead of the alternate choice in Greek of "to those set apart" and "by Christ Jesus." You cannot be sanctified if you are only called to be saints, but you can be set apart, called out of the world to seek Him and to become a saint. Those in Corinth were not sanctified. One believer was sleeping with his father's wife; other believers were quarrelling about whose baptism was the best, Paul's or Apollos'; others were suing each other in the courts. Paul said that the Corinthian believers were still carnal, (fleshly, captive to the sins of the flesh), with envy, strife, and divisions among them, 1 Cor 3:3, which is mutually exclusive with being sanctified, justified, in Christ, holy, cleansed, pure, perfect, or saved.
George Fox writes of when you are sanctified in his writing The Great Mystery of the Great Whore Unfolded:
"a believer that is justified is a new creature, is past from the death which came by sin, and comes to enter into His rest, where there is no sin. He who is the sanctification, is the justification, and so by their sanctification are they justified; it is one and the same, what sanctifies, justifies....Men are justified by the believing, and in the faith and by the faith, and in believing they overcome, and have victory; and there are mortification, and sanctification, and redemption, and justification, all possessed together in the one, which is Christ, and this to the particular satisfaction.
