Acclaimed spiritual writer Fr. Wilfrid Stinissen presents insightful reflections on the Holy Spirit, the third Person of the Holy Trinity, emphasizing the importance of the Spirit in the life of a Christian. He illustrates that the Holy Spirit desires to live in us so that we can love God and others with God's own love. As the Holy Spirit descended upon the early Church at Pentecost to set the world ablaze with the fire of divine love, so He wants to do with us.

God, who is One, also desires the Church to be one, Fr. Stinissen writes. The Lord wants to unify all Christians in one holy Church, and all people in one body. The Holy Spirit is the great unifier, he says, for it is he who makes the Father and the Son one God. If Christians let him live within them, they will grow in unity.
