1. Justification is defined as the forensic declaration that believers are righteous, rather than the process by which they are made righteous, involving a change in their status rather than in their nature.
2. A delibrate and systematic distinction is made between justification (the external act by which God declares the sinner to be righteous) and sanctification or regeneration (the internal process of renewal within humans). Although the two are treated as inseparable, a notional distinction is thus drawn where none was conceded before.
3. Justifying righteousness, or the formal cause of justification,is defined as the alien rightousness of Christ, external to humans and imputed to them, rather than a righteousness which is inherent to them, located within them, or which ins any sense may be said to belong to them. God's judgement in justification is therefore synthetic rather than analytic, in that there is no righteousness, within humans which can be considered to be the basis of the divine verdict of justification; the righteousness upon which such a judgement is necessarily based ins external to humans.
