The Dedication of the Orthodox Church in Lampeter is to the Three Hierarchs or luminaries of the Church

The three most great luminaries of the Three-Sun Divinity have illumined all of the world with the rays of doctrines divine and true; they are the sweetly-flowing rivers of wisdom, who with godly knowledge have watered all creation in clear and mighty streams: The great and sacred Basil, and the Theologian, wise Gregory, together with the renowned John, the famed Chrysostom of golden speech. Let us all who love their divinely-wise words come together, honouring them with hymns; for ceaselessly they offer entreaty for us to the Trinity.
