Matthew 12:37Meaning & Commentary from the Church Fathers

The Lord follows up what He had said before by moving their fears, shewing that they that have thus sinned shall receive the most extreme punishment, I say unto you, that every idle word that men shall speak, they shall give an account thereof in the day of judgment.

He then provides the witness of the Scriptures to prevent any assumption that he was speaking on his own authority. As he states, you will receive justification through your words, and by your words you will be condemned.

And the meaning is; If every idle word which does not edify the hearers is not without danger to him that speaks it, and if each man shall render an account of his words in the day of judgment, how much more shall you, who have spoken falsely against the works of the Holy Spirit, saying that I cast out dæmons through Beelzebub, render an account of your false charge?

Or such as lacks either rightness in itself, or reasons of just necessity;

The words which here follow depend on those that went before; By thy words thou shat be justified, and by thy words thou shalt be condemned. There is no doubt but that every man shall be condemned for his evil words which he speaks; but none shall be justified for his good words, unless they proceed from his inmost heart, and from a entire purpose.

From your own words, you shall be restrained, and from your own words, you shall be convicted - this truth is affirmed in the Old Testament. If individuals must answer to God for even a trivial utterance, which may seem like an innocent jest to some, how much more severe will the consequence be for blasphemy against the Holy Spirit? St. John Chrysostom points out how fair the judgment is and how gentle the requirement for response is. The Judge will render a verdict not based on the declarations of others, but on your own statements. What could be more just? For it is within your control to speak or to remain silent.

Anyone who does not stand with Christ is opposed to Him; inevitably, whether soon or later, he will turn into His adversary (for a contrasting view, see Mark 9:39-40). The deliberate and hardened refusal to acknowledge the clear manifestations of the Holy Spirit in Him will lead to no forgiveness, either in this life or in the life to come (31-32). The pronouncement of Christ about those who blaspheme the Holy Spirit, who offend Him with mere words, might seem overly harsh, yet Christ illustrates the gravity of the sin committed against the Holy Spirit, explaining why it remains unforgivable. He establishes a fundamental truth: if a tree is healthy, its fruit is also healthy; conversely, if the tree is unhealthy, its fruit is unhealthy (33).

Chrysostom describes the idle word as one that contradicts actions, misrepresents the truth, spreads slander, and is ultimately vacuous. This includes words that provoke inappropriate laughter, revealing shamefulness and obscenity. On the day of the Last Judgment, individuals will be held accountable not just for their actions but also for every sinful utterance, as these words reflect the innermost thoughts and emotions of a person.

You will be justified by your words: words are the manifestation of an individual's thoughts, emotions, and overall moral condition. They identify a person much like fruit reveals the nature of a tree. When a person’s words are sincere, truthful, devout, and uplifting, they reflect a righteous character, leading to justification in the heavenly court. Conversely, if a person's words are deceitful and lacking in godliness, they reveal a wicked heart, resulting in condemnation. However, it is crucial to understand that the judgment is not solely based on words; rather, a person is justified through faith and good works that stem from that faith, while condemnation arises from disbelief and the absence of good works, or from sinful actions.

I assure you that every careless word, meaning those that do not contribute genuinely to Christian edification, as noted by Blessed Theophylact, or those that are deceitful, defamatory, or inappropriate, as described by St. John Chrysostom, will be addressed on the day of judgment. For by your words, you will be acquitted, and by your words, you will be judged.
