The Celts have often been heralded as the saviours of the Western world for the writings, traditions and practices they preserved and maintained during the collapse of the Roman Empire. Today they still inspire through contemplative “Celtic” Christianity as well as through the revival of pagan traditions. There are roughly 3,000,000 speakers of Celtic languages across three primary nation-states in Western Europe.
People groups who speak Celtic languages
Below are two of the seven people groups who speak a Celtic language. Are you interested in one of the other five? Perhaps you’d be willing to help us complete the profiles for those people groups.
Cymry Cymraeg
Welsh speakers in Wales
Communities of Welsh speakers exist in Wales, England and Argentina. Linguæ Christi began in Wales and Caernarfon remains the hub for our work and activities.
Na Gàidheil
Scottish Gaelic speakers in Scotland
Scottish Gaelic, as the name implies, is spoken in Scotland. Linguæ Christi has had limited work among Scottish Gaelic speakers, but we’d like to send a long-term team to reconnect with partners.
