2 Corinthians 3:17-18
Now the Lord is the Spirit, and where the Spirit of the Lord is, there is freedom. And we all, with unveiled face, beholding the glory of the Lord, are being changed into His likeness from one degree of glory to another; for this comes from the Lord who is the Spirit.
One question that bugged early Christians was whether it was proper to worship the Holy Spirit. He is, so to speak, the quietest Person of the Trinity, always at work somewhere “within” or just at the corner of our eye. Christian imagery has never given us an easy and obvious picture to grasp like those of the Father or the Son. It’s hard to tell from the biblical imagery (wind, fire, water, the occasional dove) whether the Spirit is even a person. Early Church Fathers wrestled with the question of whether He was a mere “force” or some other impersonal thing, but were always constrained (by verses like today’s verses) from giving in to mere picture-thinking. The Lord, says St. Paul, is the Spirit. Moreover, the Spirit is a “who” not a “what.” And since the Lord is to be worshipped, the Lord who is the Spirit is to be worshipped. Today, worship the Holy Spirit.
