QUESTION 21
OF PRESUMPTION
(In Four Articles)
We must now consider presumption, under which head there are four points of inquiry:
(1) What is the object in which presumption trusts?
(2) Whether presumption is a sin?
(3) To what is it opposed?
(4) From what vice does it arise? _______________________
FIRST ARTICLE [II-II, Q. 21, Art. 1]
Whether Presumption Trusts in God or in Our Own Power?
Objection 1: It would seem that presumption, which is a sin against the Holy Ghost, trusts, not in God, but in our own power. For the lesser the power, the more grievously does he sin who trusts in it too much. But man's power is less than God's. Therefore it is a more grievous sin to presume on human power than to presume on the power of God. Now the sin against the Holy Ghost is most grievous. Therefore presumption, which is reckoned a species of sin against the Holy Ghost, trusts to human rather than to Divine power.
