The Holy Spirit is consistently referred to with masculine pronouns in Scripture, emphasizing His personhood, rather than describing an impersonal force. While the Hebrew word ruach is grammatically feminine, and the Greek word pneuma is neuter, these linguistic forms for "spirit" do not indicate the Spirit’s gender. The Spirit performs actions that only a person can do, such as guiding, convicting, interceding, and performing miracles. Jesus specifically calls the Spirit “He” and describes Him as a Helper, who teaches and leads into truth. Ultimately, God transcends human gender, so while it is appropriate to refer to the Holy Spirit in masculine terms, He is fully Spirit and not male or female in a human sense.
In the Bible, God the Father and God the Son, Jesus Christ, are both addressed as male. What about the Holy Spirit? Often, people refer to the Holy Spirit as "it," yet Scripture refers to the Holy Spirit as a male, just as it does for the Father and the Son. Some critics point out that the Greek word for "spirit," pneuma, is neuter (not gender specific) or that the Hebrew Old Testament word for "spirit," ruach, is used as feminine in Genesis 1:2. However, the gender of a word in Hebrew or Greek does not specifically indicate the gender of what the word identifies. As an example, in English, we often refer to a boat or a nice car as "she" (as in, "Ain't she a beauty?"). However, the boat itself is not female.
But is the Holy Spirit male, female, or neither? From a grammatical standpoint, the words used to refer to the Holy Spirit are consistently masculine. Theologically speaking, we must remember that God is not human, and therefore, does not fit within our definitions of male or female. It is appropriate to speak of the Holy Spirit in male terms, as Scripture does, but we must understand that God is wholly other and does not exist in the same form as we do (with the exception of Jesus as God in human form).
There is no justification for belief in a female member of the Trinity. However, God is Spirit and exists in a form that defies male/female categories. The Bible uses masculine terms to refer to the Holy Spirit. The Spirit is a "He," not an "it" or a "she."
