Whether presumption is a sin?

❌ Objection 1 : It would seem that presumption is not a sin. For no sin is a reason why man should be heard by God. Yet, through presumption some are heard by God, for it is written (Judith 9:17): "Hear me a poor wretch making supplication to Thee, and presuming of Thy mercy." Therefore presumption on God's mercy is not a sin.

❌ Objection 2 : Further, presumption denotes excessive hope. But there cannot be excess of that hope which is in God, since His power and mercy are infinite. Therefore it seems that presumption is not a sin.

❌ Objection 3 : Further, that which is a sin does not excuse from sin: for the Master says (Sent. ii, D, 22) that "Adam sinned less, because he sinned in the hope of pardon," which seems to indicate presumption. Therefore presumption is not a sin.
