There are two holy spirits in the gospels.
In the Gospels, two holy spirits are described: the spirit of God that came upon Christ, and the Spirit of Christ on Mary. This was the Holy Spirit that Jesus breathed into His disciples.
How can the Spirit of Christ can be manifest in Christ and still be active in other people? Paul said that Christ was only “found in appearance as a man” (Philippians 2:8), “revealed in the flesh” (I Timothy 3:16), just as the Spirit of Christ was only found in appearance as an angel in the Old Testament. This was dramatically illustrated for us in the first Chapter of Revelation, where the Spirit of Christ appeared as the Angel of God and the Son of Man at the same time.
In the New Testament, “Spirit” with the article can describe a spirit as a being, just as it did in the Old Testament. The Apostles also used the article to identify the Spirit of the Lord. Paul said, “the Lord is the Spirit” (2 Corinthians 3:17). In the Gospels, while God was “the Lord,” the spirit of God was called “the spirit.”
The expression “spirit” without the article describes the “anointing of the holy spirit.” In Matthew, Jesus said, “How then does David in spirit call Him, Lord” (Matthew 22:43). But Mark records this as, “David himself said by the Holy Spirit …” (Mark 12:36). “Spirit” described the anointing of the Spirit of Christ before the Day of Pentecost, and the anointing of the spirit of God on Christ.
After the Day of Pentecost, the Spirit of Christ was described as “the Spirit,” and the spirit of God was described as “spirit.”
John said, “by this He spoke of the Spirit (the Spirit of Christ) which those who believed in Him were about to receive, for spirit (the spirit of God) was not yet given because Jesus was not yet glorified” (John 7:39).
