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:

A1 Whether the sacraments of the New Law are the cause of grace?

A2 Whether sacramental grace confers anything in addition to the grace of the virtues and gifts?

A3 Whether the sacraments contain grace?

A4 Whether there is any power in them for the causing of grace?

A5 Whether the sacraments derive this power from Christ's Passion?

A6 Whether the sacraments of the Old Law caused grace?
