Papal Encyclicals on the Holy Spirit

The Holy Spirit (depicted in the window of the apsis) dominates the Throne of Saint Peter -
by BERNINI, Gian Lorenzo, from San Pietro, Rome

Paraclete (Latin <Consolator>; Greek <Parakletos>), an Appellation of the Holy Ghost. Variously translated "Advocate", "Intercessor", "Teacher", "Helper", "Comforter". According to St John, the Mission of the Paraclete is to Abide with the Disciples after Jesus has withdrawn His Visible-Presence from them; to Inwardly Bring-home to them the Teaching Externally given by Christ and thus to Stand as a Witness to the Doctrine and Work of the Savior. There is no reason for limiting to the Apostles themselves the Comforting Influence of the Paraclete. The Paraclete Comforts the Church by Guaranteeing her Inerrancy and Fostering Her Sanctity. He Comforts each Individual Soul in many ways. Every Salutary Condition, Power, and Action, in fact the Whole Range of our Salvation, comes within the Comforter's Mission. Its Extraordinary Effects are styled Gifts, Fruits, Beatitudes. Its Ordinary Working is Sanctification with all it entails, Habitual Grace, Infused Virtues, Adoption, and the Right to the Celestial Inheritance. "The Charity of God", says St Paul, "is Poured-forth in our Hearts by the Holy Ghost Who is given to us". In that Passage the Paraclete is both the Giver and the Gift: the Giver of Grace (<Donum Creatum>) and the Gift of the Father and the Son (<Donum Increatum>). St Paul teaches repeatedly that:

the Holy Ghost dwells in us.

( If you are in the State of Sanctifying Grace,
the Holy Ghost dwells 'in-you'
in a very Special and Personal way. )

The Supernatural Order is the Ensemble of Effects exceeding the Powers of the Created Universe, and Gratuitously produced directly by God for the purpose of Raising the Rational Creature above its Natural Sphere to a God-like Life and Destiny.

by Pope Leo XIII, Pope Pius XII, and Pope John Paul II

Faith in the Holy Spirit, Uninterruptedly-Professed by the Church, needs to be Constantly Reawakened and Deepened in the Consciousness of the People of God. In the Course of the Last Hundred Years this has been done Several Times:

by Pope Leo XIII, who Published the Encyclical Epistle Divinum Illud Munus (On the Holy Spirit) (9 May 1897) entirely devoted to the Holy Spirit;
by Pope Pius XII, who in the Encyclical Letter Mystici Corporis (1943) spoke of the Holy Spirit as the Vital Principle of the Church, in which He works in Union with the Head of the Mystical Body, Christ;
by Pope John Paul II, who in the EncyclicalDominum et vivificantem (Lord and Giver of Life) (5 May 1986) professes the Faith of the Church in the Holy Spirit as "the Lord, the Giver of Life"
by Pope John Paul II, who in his Pentecost Homily Veni, Sancte Spiritus (Come, Holy Spirit)(1998) proclaims the Faith of the Church in the Paraclete, a Faith that is born of the Apostolic Experience of Pentecost.
by Pope John Paul II, who in his Pentecost Homily The Holy Spirit Sends Us to Proclaim the Gospel (2000) says that the Holy Spirit gave the Apostles the necessary Light and Strength to teach the Nations and to proclaim Christ's Gospel to them all. In this way the Church was Born and Lives in the Fruitful Tension between the Upper Room and the World, between Prayer and Proclamation.
by Pope John Paul II, who in his Homily Faith is the Work of the Holy Spirit (15 August 2000) recommends that we let ourselves "be Molded by the Holy Spirit".
