This paper examines art as a flourishing form of contemporary spirituality and as part of a wider socio-cultural transformation often referred to as the post-secular turn. Christian theology has often interpreted this realm in terms of incarnation and sacraments, as these are the two theological loci where the union of the material and the spiritual is most fully realised, mirroring the structure of many artistic expressions. However, if these doctrines are to be more than an analogy, they must be stretched so far that virtually anything can become an incarnation or a sacrament. As such, they lose all specificity, rob Christ of his personal identity, and turn him into a transpersonal principle embodied in works of art or other phenomena. To avoid this trap, the paper argues that if one is concerned with the spiritual in art, as Wassily Kandinsky was at the beginning of the last century, one must also consider the Spirit. The Holy Spirit is seen as a medium of God's communication with the world, responding to and inspiring human communication, the specific form of which is art. The intersection of these communications takes place both inside and outside institutional religion and is not based on the presupposed universality of Christ or the sacraments.
