For this Third Person of the Trinity is the very Breath of the Word of God — the very Lord Who is Himself the Spirit. Only in a Spirit-ual way does the Father communicate with His Son or with mankind — and, indeed, precisely within history.
Accordingly, if there is to be any communication at all between man and the Triune God, the Latter must be worshipped by the former — in Spirit. For God is Spirit. And the Spirit is Divine. Indeed, the Holy Ghost or Spirit — being God — is creative, omnipresent, omniscient, and eternal.
