The lecture discusses the danger of speech and the faults of the tongue, and affirms that a person’s speech is not a trivial matter but a manifestation of what is in the heart; the tongue reveals the heart and shows what is inside.

Main points

• The tongue reflects the inner treasure: what comes out of the mouth indicates the state of the heart (love, anger, envy, hardness, wrath).

• The sin of the tongue is double: it is a sin of the heart and leads to judgment and accountability.

• Speech sometimes defiles a person and is recorded and does not return to the mouth — the spoken word is not easily taken back.

• Haste in speech is a major cause of error; examples from the Holy Scripture show effects of a hasty word (example: His Holiness Pope Shenouda III speaks about Peter and historical examples).

• Three wrong ways of conveying speech: conveying it as is, conveying it with a wrong meaning, and inventing speech — and the most dangerous is conveying secrets and spreading them.

• Results of speech: destroying relationships, igniting disputes, spreading heresy and wrong teaching, cooling or warming the spirit by words.

• Types of tongue faults: blasphemy, cursing, gloating, mockery, insult, wrong advice, harsh teasing, revealing others’ secrets.

• Importance of silence and guarding the mouth: fasting without guarding the tongue is null; the saints loved caution and silence and asked God to open the lips for good speech.

• Practical guidance: be quick to listen, slow to speak, weigh your words and think of their consequences before uttering them, and consult the confessor for spiritual counsel.

Spiritual / educational dimension (from a Coptic Orthodox faith perspective)

The lecture calls the believer to practical repentance: first watchfulness of the heart and then guarding the tongue as the fruit of repentance. It highlights keeping the spiritual aspect of fasting (controlling the tongue) as part of the spiritual life, and turning to prayer and confession so that speech is filled with divine words instead of harmful speech. The tongue here is a soteriological matter because the word produces spiritual and social consequences that continue and are accounted for before God.
