In studying the Reformed view of Sanctification I came across the idea of "Definitive Sanctification." Definitive Sanctification seems to refer to our ability to be sanctified, or more clearly to sanctify or purify ourselves. I cannot seem to understand the need for this terminology as a distinct idea from Regeneration. If there is a functional purpose for the term Definitive Sanctification I would appreciate someone clearing it up for me. If there is not, is there really a need to clutter up the already complicated jargon of theology?
