In a certain sense, my previous Encyclicals Redemptor Hominis and Dives in Misericordia took their origin and inspiration from this exhortation, celebrating as they do the event of our salvation accomplished in the Son, sent by the Father into the world "that the world might be saved through him" and "every tongue confess that Jesus Christ is Lord, to the glory of God the Father." From this exhortation now comes the present Encyclical on the Holy Spirit, who proceeds from the Father and the Son; with the Father and the Son he is adored and glorified: a divine Person, he is at the center of the Christian faith and is the source and dynamic power of the Church's renewal.(#2)
The Holy Spirit does not disappoint, though many doubted (even to this day) the message of Wojtyla concerning VCII, Communism/Socialism, Marriage and Celibacy, etc. Thankfully, the catechsim refers to the "Living Memory of the Church" being the Holy Spirit-Advocate who has preserved the writings of St. John Paul II (even in his own native Polish) so that there can be no doubt about his being inspired by the 3rd Person of the Trinity.
