We live in a culture where speech, especially public speech, has progressively been coarsened. The television ‘watershed’ excludes less and less offensive speech, performative profanity is now de rigueur for many celebrities and even some politicians, and there has emerged a real generational divide between those of my generation and the baby-boomers. We appear to have forgotten a basic rule that the ancients knew all too well: affect has effect. What you say influences who you are.
What we say, just as what we do, impacts the sort of person we become and the virtues (or lack of them) that we build up and possess. If we look to Aristotle, we are introduced the concept of habitus. It isn’t just a habit – not just an activity that we engage in on a regular basis – but is a repeated behaviour that builds up our character, for good or for ill. This idea was taken up in some form by Augustine, Averroes, Aquinas, and even people whose name doesn’t begin with the letter A. Our speech, if repeated over and over again, moulds our character. Kind speech, lovely speech, righteous speech – repeated ad nauseum – will have as their end product a kind, a lovely, a righteous person. Violent speech, aggressive speech, coarse speech, will have as their end product a violent, aggressive, and a coarse version of the same.
Going beyond Aristotelian categories to biblical ones, the use of language is often a favourite theme. The most famous Hebrew example is perhaps the commandment: “Thou shalt not take the name of the LORD thy God in vain…” Our speech is important to God, because it is a basic indicator of how we conduct ourselves – and so an indicator of who we are – and we ought to be conducting ourselves in the light of God’s will and God’s law: “Let the words of my mouth, and the meditation of my heart, be acceptable in thy sight, O Lord, my strength, and my redeemer.”
As we move from the Old Covenant to the New, we find St Paul continuing this idea and extending the principle – our words reflect our relationship with God, and so will impact our relationship with other people (who are made in His image). He asks the Colossians that they speak ‘always with grace’, tells the Ephesians to avoid ‘filthiness…foolish talking…jesting’, and commands the Romans to always have a word of blessing ready rather than a curse. The community of holy people, living a life for God and for each other, can easily be destroyed by a cruel slip of the tongue – a fight can break out over even a mild insult. Perhaps this is why Jesus is quite so strict about speech – “But I say unto you, That every idle word that men shall speak, they shall give account thereof in the day of judgment.” He is very clear in teaching people that the words that leave their mouths have the power to bless them or damn them.
