Article IV - Of the Holy Ghost
The Holy Ghost, proceeding from the Father and the Son, is of one substance, majesty, and glory with the Father and the Son, very and eternal God.
Ghost is such a strange word to the modern tongue. My first thought is Caspar the friendly ghost, but that really refers to is the connection between ghosts and the souls of the dead who are neither in heaven nor in hell. This is not a biblical notion, but it is quite popular. Shows like Ghost Hunter and Ghost Whisperer point to a collective fascination with this possibility (not to mention A Christmas Carol or Hamlet).
Today, we mostly speak of the Holy Spirit, but Holy Ghost refers to the exact same thing. Ghost comes from an Old English root whereas Spirit comes from a Latin root, both refer to immaterial realities. Realities without substance or matter.
So what does the Holy Spirit have to do with my life?
Jesus tells us quite explicitly in the Gospel of John: “But the Advocate, the Holy Spirit, whom the Father will send in my name, will teach you all things and will remind you of everything I have said to you.” The Holy Spirit is the Love between the Father and the Son, the Holy Spirit is the bond that connects the church to God.
In the Methodist tradition, we believe that the Holy Spirit is present with us from before we are even aware of God. We call this prevenient grace (which means the grace that comes before). When we say Yes to God, it is because God has said yes to us through the Holy Spirit. But more than that, the Spirit that is with us is not simply a messenger of God but is true God from true God.
We see a connection between the creation with the Spirit or breath (Ruach) of God flowing over the waters to bring forth life. We see the Spirit with Moses and the Bush, and with Jesus, the Spirit that descends, the Spirit that is sent out, the Spirit that is with us today.
The reason why the church exists, why this church exists, is not due to the extraordinary actions of a few individuals but because God is with us through the Holy Spirit. If the Spirit were not with us, if the Spirit were not God, we would be alone to the whims of a tyrant like Zeus rather than the creator who is love.
