We now look at the third person of the Trinity: the Holy Spirit - helper, consoler, Lord and giver of life. The hidden work of the Holy Spirit from creation to the coming of the Messiah. The Holy Spirit's special relationship with Mary, mother of Jesus. Jesus lived in the fullness of the Holy Spirit, and He promised to send the Spirit to his disciples after He would leave them. The Holy Spirit was outpoured on the Church at Pentecost - God's sanctifying love poured out into our hearts. The work of the Holy Spirit in the Church and how we can receive Him.
