The Holy Spirit is, first of all, the minister of communion. Communion as spoken of in scripture is more than toleration, or being polite, or being deferentially inclusive. Communion has to do with the inner life of God.
Communion is that which is shared between the three persons of the Holy Trinity.
Through baptism we are taken into that circle dance. The Holy Spirit, minister of communion, pours the love of God into our hearts and gives us the ability to respond to God's love with our own answering love. Our answering love is the Spirit of Christ loving the Father in and through us. So we are constituted to live lives of communion. We can only be real as people as we live lives of communion.
