We have now to consider the effect of the sacraments.
First of their principal effect, which is grace; secondly, of their secondary effect, which is a character.
Concerning the first there are six points of inquiry:
A Whether the sacraments of the New Law are the cause of grace?
A Whether sacramental grace confers anything in addition to the grace of the virtues and gifts?
A Whether the sacraments contain grace?
A Whether there is any power in them for the causing of grace?
A Whether the sacraments derive this power from Christ's Passion?
A Whether the sacraments of the Old Law caused grace?
