5.3 The Holy Spirit in Christianity
For Christians, the Holy Spirit represents God’s continuing presence and activity in the world.
Jewish Roots and the Earliest Christians
Jesus, His disciples, and the earliest Christians were Jews who inherited the Jewish belief that God’s Spirit was active in creation, prophecy, wisdom, guidance, and the lives of God’s people.
For this reason, the earliest followers of Jesus most likely understood the Spirit of God largely through the categories already present in the Hebrew Scriptures: God’s presence, power, wisdom, inspiration, and activity in the world.
Over time, as Christian theology developed, most Christians came to understand the Holy Spirit as the third person of the Trinity: fully divine, distinct from the Father and the Son, and personally relational in the lives of believers. This became the dominant view in Catholic, Orthodox, and most Protestant Christianity.
Other believers understand the Holy Spirit in ways that emphasize God’s presence, power, wisdom, activity, or holy influence within creation and human life.
Pentecost
In Christianity, one of the most important events involving the Holy Spirit is Pentecost. According to the book of Acts, Jesus’ followers gathered together after His ascension and experienced an outpouring of God’s Spirit.
Acts 2 describes a sound like a mighty rushing wind, appearances like tongues of fire, and the disciples being filled with the Holy Spirit. This event is often viewed as the beginning of the Christian church and serves as a foundational moment in Christian understanding of the Holy Spirit.
Throughout the New Testament, the Holy Spirit is described as teaching, guiding, comforting, empowering, and transforming believers. The Spirit is associated with repentance, spiritual growth, moral transformation, and the development of virtues such as love, patience, faithfulness, and self-control.
The New Testament also occasionally refers to the Holy Spirit as the Spirit of Christ, the Spirit of Jesus, or the Spirit of God’s Son. These expressions helped shape later Christian discussions about the relationship between God, Christ, and the Holy Spirit.
While Christians generally agree about the importance of the Holy Spirit, they do not all agree on exactly how the Holy Spirit should be understood.
The Trinitarian View
The most common view within Christianity today is the Trinitarian view.
According to this understanding, the Holy Spirit is the third person of the Trinity, fully divine and distinct from both the Father and the Son while sharing the same divine nature. After Jesus ascended to heaven, the Holy Spirit was sent to dwell within believers. He acts as a counselor, comforter, and guide, making God’s presence personally felt in daily life. He also alerts a believer’s conscience to sin and points them toward repentance.
One of the most influential creedal statements about the Holy Spirit developed in connection with the Council of Constantinople in AD 381, which was summoned under the Roman emperor Theodosius I. The creed helped establish the classical Trinitarian understanding of the Holy Spirit that would later become dominant throughout most of Christianity. This creed is recited weekly by hundreds of millions of Catholic, Orthodox, and Protestant Christians today. It explicitly calls the Holy Spirit “the Lord, the Giver of Life, who proceeds from the Father [and the Son], who with the Father and the Son is worshiped and glorified.” Western versions add “and the Son.”
From the Trinitarian perspective, when the New Testament describes the Spirit as teaching, guiding, speaking, interceding, and comforting, these actions are evidence that the Holy Spirit is fully God—a distinct and divine person. These believers typically hold that the Spirit was not created. He existed before time and was active in the creation of the universe.
Trinitarians emphasize that the Holy Spirit has personality, volition, and emotion. They point to New Testament passages showing that the Spirit can speak, teach, grieve when people sin, make decisions, intercede, and pray on behalf of believers. These believers also point to passages in which the Spirit gives instructions, sends individuals on specific missions, and directs the growth of the early church.
The Spirit of Holiness and Transformation
As previously discussed, spiritual language can operate on multiple levels. A spirit may refer to a personal, invisible, and conscious being, but it may also refer to an invisible pattern of motivation, attitude, perception, and behavior that shapes how people interpret reality and respond to it. In this sense, a “spirit” is an organizing influence that can direct a person’s thoughts, desires, emotions, words, and actions.
Some Christians therefore understand references to the Holy Spirit as describing God’s holy influence working within individuals. Under this interpretation, the Holy Spirit is not a person but rather understood as the Spirit of holiness itself—the perceptions, motivations, and patterns of thought that draw people toward holiness, truth, wisdom, repentance, love, courage, justice, faithfulness, and moral transformation.
The emphasis in this view is the observable transformation of a person’s life toward integrity. The Holy Spirit is seen as the desire and influence by which a person becomes increasingly aligned with God’s character and will. Their conscience becomes more responsive to truth. Their desires become more ordered toward goodness. Their actions produce the visible signs of holiness in daily life.
Different Interpretations
Suppose a person becomes more truthful, more courageous, more loving, more self-controlled, more responsible, and more just over several years. A Jewish interpretation might say that God worked through His Spirit in that person’s life. A Trinitarian Christian might say that the Holy Spirit transformed the person from the inside. Someone who understands the Holy Spirit as the Spirit of holiness might say that the person became increasingly aligned with God’s Spirit, and that this alignment reordered their conscience, motivations, desires, and behavior.
There are other minority views about the Holy Spirit as well. Different interpretations often arise because the biblical descriptions of the Spirit are diverse.
Despite their disagreements, most Christians agree about the importance and practical work of the Holy Spirit. The Spirit is believed to draw people toward God, convict them of wrongdoing, guide them toward truth, strengthen them during hardship, and help them develop a more faithful and righteous way of life.
For this reason, discussions about the Holy Spirit are often connected to two important questions:
- What does it mean to receive or be filled with God’s Spirit?
- What changes should be visible in the life of a person who is influenced by God’s Spirit?
These questions have led Christians to develop teachings about the baptism of the Holy Spirit, spiritual gifts, and the fruits of the Spirit, which we will examine in the next sections. In section 5.4, we will look at what Christians mean by receiving, being filled with, or being baptized in the Holy Spirit.
