Commentators like Calvin and Spurgeon see Peter's action as a classic example of "foolish zeal." While his loyalty was commendable, his impulsive violence was contrary to God's will. Calvin warns that zeal, no matter how sincere, becomes sinful when it's not guided by obedience to God's word. This serves as a powerful reminder for believers to ensure their passion for God is channeled through wisdom and submission, not carnal means.
