God is Spirit
Preliminary:
Immortal, invisible God only wise,
In light inaccessible hid from our eyes,
Most blessed, most glorious, the Ancient of Days,
Almighty, victorious, Thy great name we praise.
a few languages the equivalent of Spirit is literally ‘shadow,’ since the ‘shadow’ of a person is regarded as the immaterial part of the individual. Moreover, in many systems of religious thought the shadow is regarded as having some significant measure of independent existence.
Frequently it is not possible to find a fully satisfactory term for ‘Spirit,’ and therefore in all contexts some characterizing feature is added, for example, either ‘of God’ or ‘holy,’ in the sense of ‘divine.’ This may be particularly necessary in a passage such as Mk 1:12 where the average reader might assume that a spirit which would make Jesus go out into the desert would be an evil rather than a good spirit.
Assignment of human attributes to nonhuman things.
The use of human terminology to talk about God is necessary when we, in our limitations, wish to express truths about the Deity who by his very nature cannot be described or known. From biblical times to the present, people have felt compelled to explain what God is like, and no expressions other than human terms are able to convey any semblance of meaning to the indescribable.
The attribute of God’s spirituality must be distinguished from the Third Person of the Trinity, the Holy Spirit. The eternal Father, Son, and Spirit are all “spiritual” in nature (excepting, of course, the incarnate Son in his human nature). Although angels are spiritual beings and humans are physical-spiritual beings, God’s spirituality is an incommunicable attribute in that his spirituality is both infinite and uncreated, while all other spirits are created and therefore finite.
