English Orthodox iconographer Aiden Hart writes well of his craft. He includes photos of the very beautiful chapel he has created at the Hermitage of Saint Anthony and Saint Cuthbert, Shropshire, England:
That is to say, spiritual things need explaining or manifesting in a spiritual way. So what makes icons and other good liturgical arts so powerful is not just their sacred subject matter, but the way this subject matter is expressed. An icon crudely or sentimentally painted still acts as an icon inasmuch as it connects us with its prototype through the saint’s name that it bears. But it fails inasmuch as its “style” or language does not satisfactorily evoke the transfigured world. Similarly, a church building can protect the congregation from the elements but by poor design fail to give them the sense of the incarnate God dwelling in their amidst.
To see with the eye of the heart we need first to be purified, to repent, to turn towards God. Liturgical art can assist this turning through its “joyful sorrow”.
