The Holy Spirit is the most obscure of the three Persons of the Trinity, not that the other Persons aren’t mysterious as well. One reason is that the Son is said to show the Father, and the Holy Spirit is said to show the Son, but that leaves nobody to show the Holy Spirit. So obscure is the Holy Spirit that it is difficult to think of the Holy Spirit as a Person at all. It is not uncommon to hear the Holy Spirit referred to as “it,” although both masculine and feminine pronouns also fall far short of the Holy Spirit’s personhood.
It is easier to sense some personhood for the Father and the Son because their relationship is defined by filiation, that is, the Father begetting the Son has a personal analogy in human experience. But the Holy Spirit’s relationship to the other Divine Persons is through spiration, that is breathing. We think of breath as a human function rather than a person in his or her own right. The Holy Spirit is often called the “Bond of Love” between the Father and the Son. This is a beautiful phrase but again, it doesn’t give the Holy Spirit a personality. If we say two people are bonded in love, we think of the bond as something between the two people, not a third person.
Since it is a sure thing that the Holy Spirit is a Person, however obscure, and however mysterious, then perhaps we can take these rather impersonal images and analogies and personalize them.
The Holy Spirit as breath, the Person spirated, or breathed, by the Father and the Son is associated with inspiration. The Holy Spirits’s inspiration in its gentler form is symbolized by a dove in scripture, most importantly at Jesus’ baptism, where the image accompanies the heavenly voice acclaiming Jesus as the Son of the heavenly Abba. At Pentecost, the Holy Spirit appears as flames of fire inspiring the disciples to preach in the languages of the pilgrims from foreign countries. In all this, we have, again, impersonal images, except insofar as birds can show some elements of personality. In all this, however, we can see the Holy Spirit revealed as a Divine Person who inspires and energizes. In fact, the Holy Spirit inspires by distributing various gifts to various people, enhancing both the individuality of people and our connectedness as we exchange these inspired gifts to each other. Through this exchange of gifts, we can inspire others with our insights and enthusiasms. We can think of the inspiring teachers and preachers who have energized us to spread that same enthusiasm and inspiration to others. This is what the Holy Spirit does.
The Holy Spirit as the bond of love between the Father and the Son can also be understood in a personal way. That is, the Holy Spirit is a Person who actively encourages love between other people. Humans can act as such a bond of love. Friar Lawrence plays such a role in Romeo and Juliette. In South Pacific, Bloody Mary encourages the love between Col. Talbot and the Polynesian woman in the song “Happy Talk,” while Col. Talbot himself struggles with his racist heritage in “Carefully Taught.” As these go-betweens try to help lovers overcome obstacles (scandals), so the Holy Spirit encourages all of us to overcome all obstacles to loving relationships.
In the Upper Room, Jesus breathes the Holy Spirit into the apostles and then commissions them to spread forgiveness to other people. (Jn. 20: 23) (I don’t think Jesus wants us to retain the sins of others.) Here we have the Holy Spirit as the Person who inspires, encourages, forgives, and reconciles. In all of these acts, the Holy Spirit remains hidden, showing other people to us and us to other people. At the same time, the Holy Spirit shows us the Son in other people and shows the Son in us to others. If we wish to really honor and celebrate the Holy Spirit, we, too, will go and inspire, encourage, forgive, and reconcile others.
