Whether pride is a sin?

❌ Objection 1 : It would seem that pride is not a sin. For no sin is the object of God's promise. For God's promises refer to what He will do; and He is not the author of sin. Now pride is numbered among the Divine promises: for it is written (Is. 60:15): "I will make thee to be an everlasting pride [Douay: 'glory'], a joy unto generation and generation." Therefore pride is not a sin.

❌ Objection 2 : Further, it is not a sin to wish to be like unto God: for every creature has a natural desire for this; and especially does this become the rational creature which is made to God's image and likeness. Now it is said in Prosper's Lib. Sent. 294, that "pride is love of one's own excellence, whereby one is likened to God who is supremely excellent." Hence Augustine says (Confess. ii, 6): "Pride imitates exaltedness; whereas Thou alone art God exalted over all." Therefore pride is not a sin.

❌ Objection 3 : Further, a sin is opposed not only to a virtue but also to a contrary vice, as the Philosopher states (Ethic. ii, 8). But no vice is found to be opposed to pride. Therefore pride is not a sin.
