QUESTION 65
OF THE NUMBER OF THE SACRAMENTS
(In Four Articles)
We have now to consider the number of the sacraments: and concerning this there are four points of inquiry:
(1) Whether there are seven sacraments?
(2) The order of the sacraments among themselves;
(3) Their mutual comparison;
(4) Whether all the sacraments are necessary for salvation? _______________________
FIRST ARTICLE [III, Q. 65, Art. 1]
Whether There Should Be Seven Sacraments?
Objection 1: It seems that there ought not to be seven sacraments. For the sacraments derive their efficacy from the Divine power, and the power of Christ's Passion. But the Divine power is one, and Christ's Passion is one; since "by one oblation He hath perfected for ever them that are sanctified" (Heb. 10:14). Therefore there should be but one sacrament.
