What are the denominational differences concerning the reformed doctrines of grace?

The question is stemming from what looks like a complete blanket of grace not only concerning the reception of salvation, but also being applied to the process of sanctification without limitations. There are different views on the grace that is gifted and exactly what it applies to. For example evangelicalism applies total grace to salvation and sanctification, even if someone is apostate, while others don't do that. Others limit grace to those who stay in repentance. What are the main differences concerning grace between church factions and how do they justify their beliefs according to their doctrine and scripture? Philippians 2:12 - "Therefore, my beloved, as you have always obeyed, not as in my presence only, but now much more in my absence, work out your own salvation with fear and trembling" There are some passages like Ph 2:12 that make it sound like grace being attached to sanctification is conditional based on obedience. This is not about what grace is, but how it's taught differently and applied from denomination to denomination.
