Union with the Whole Christ
Against the objection that, in terms of sola fide, one could theoretically receive Christ for justification but not for sanctification and thus stand forgiven in Christ while devoid of good works- Calvin vigorously rejected the situation as theologically impossible. One does not in practice take Christ for justification itself or sanctification itself for these are not independent realities to be grasped. One is not united to justification or sanctification. Rather, one receives and is united to Christ, in whom these blessings reside. Therefore, to be united to Christ is necessarily to be made a partaker of all his blessings, not merely a few.
