The Dangers of Boasting in One's Faith and Its Consequences
James warns that boasting in presumptions is evil [1], a judgment that reflects a broader biblical concern about the spiritual peril of self-exaltation in matters of faith. The danger lies not in legitimate testimony to God's work but in the arrogance that displaces divine sovereignty with human confidence. Paul acknowledges that boasting may sometimes be necessary, yet immediately qualifies it as unprofitable [2, 3], suggesting that even when compelled to speak of spiritual experiences, the posture must remain one of humility rather than self-promotion.
The Nature of Sinful Boasting
Aquinas distinguishes between boasting as venial and mortal sin based on its object: when a person boasts of something contrary to God's glory—claiming divine prerogatives, for instance—the sin becomes mortal because it directly opposes charity and usurps what belongs to God alone [4]. The prophet Ezekiel's condemnation of the king of Tyre, who declared "I am God," exemplifies this extreme form [4]. The Reformed tradition similarly emphasizes that any human arrogation, "however minute," robs God of his honor and subjects the boaster to a fall [6]. Calvin warns that man cannot claim credit for himself without this dual consequence: dishonoring God and inviting spiritual collapse [6].
Consequences in Community and Doctrine
The consequences extend beyond individual pride to communal destruction. Paul's warning to the Corinthians identifies jealousy, argumentativeness, and divisiveness as forces that destroy God's temple—the body of believers—with "terrible consequences" for those responsible [5]. Boasting in one's theological acumen or spiritual status fractures the unity that marks the church as holy. The heathen philosophers who professed themselves wise became fools [8], a pattern that recurs whenever religious error masquerades as wisdom and demands credit for itself [8].
The Remedy
Augustine cautions that misinterpreting Scripture out of attachment to one's own opinion breeds anger toward the text itself rather than self-correction [11]. The antidote is the recognition that faith depends not on human imagination but on God's testimony [10], and that forgiveness precedes any work God regards favorably [9]. The preaching of predestination and the call to persevering faith form two parts of one message [7], both designed to prevent the twin errors of presumption and despair. Boasting collapses when believers grasp that their standing rests entirely on divine initiative, not personal achievement.

I answer that, As stated above (Question [110], Article [4]), a mortal sin is one that is contrary to charity. Accordingly boasting may be considered in two ways. First, in itself, as a lie, and thus it is sometimes a mortal, and sometimes a venial sin. It will be a mortal sin when a man boasts of that which is contrary to God's glory---thus it is said in the person of the king of Tyre (Ezech. 28:2): "Thy heart is lifted up, and thou hast said: I am God"”

Eph 2:21-22), and God’s temple is holy (see 1 Cor 1:2). There are terrible consequences for anyone who destroys God’s temple by such things as jealousy, argumentativeness, and divisiveness (see 3:3-4).”

On the other hand, man cannot arrogate any thing, however minute, to himself, without robbing God of his honour, and through rash confidence subjecting himself to a fall. To keep free of both these ”

- CCEL (Reformed) “John Calvin, Institutes of the Christian Religion, section 69: imputes sin are enemies, and, therefore, our sins must be covered and forgiven before the Lord has respect to any of our works. From this it follows, that the forgiveness of sins is gratuitous, and this forgiveness is wickedly insulted by those who introduce the idea of satisfaction. Let us, therefore, after the example of the Apostle, “forgetting those things which are behind, and reaching forth unto those things which are before,” “press toward the mark for the prize of the high calling of God in Jesus Christ,” ( Phil. 3:13, 14 )”

Hence again we infer, as has already been explained, that faith has no less need of the word than the fruit of a tree has of a living root; because, as David testifies, none can hope in God but those who know his name ( Ps. 9:10 ). This knowledge, however, is not left to every man’s imagination, but depends on the testimony which God himself gives to his goodness. This the same Psalmist confirms in another passage, “Thy salvation according to thy word,” ( Ps. 119:41 ). Again, “Save me,” “I hoped in thy word,” ( Ps. 119:146, ”
