@KorvinStarmast I have personal stake in researching charismatic movement as I personally see excesses in charismatic movement both Catholic and Protestant circles, which in Catholicism manifest itself in "shift the focus of worship away from reverent communion with Christ in the Eucharist and towards individual emotions and non-liturgical experiences as a substitute" (wikipedia) while in Protestant circles draw attention away from growing fruits of the Spirit, esp. love one another.

@KorvinStarmast Therefore, I welcome the successive Popes to "test the Spirit" while not "quenching the Spirit". I also welcome the "old guard" warning represented by this answer since I remain committed to Thomistic view of how grace perfects nature, of the faculties of the soul, of virtues, of the 3 transcendentals, etc.

@KorvinStarmast But I also appreciate "modernist" attention on subjective experience which I think should be integrated into one whole, so I'm watching closely how Pope John Paul II and Pope Benedict XVI do it, who I think have done an admirable job in being scholarly, faithful to the apostolic tradition, and responsible in shepherding and nurturing and uniting Catholics of all stripes, not to mention inviting Christians from outside the Catholic church like myself.

@KorvinStarmast To aid discernment of what's authentic, I especially welcome studies like this 2011 thesis 'Baptism in the Holy Spirit': A Phenomenological and Theological Study' which attempts "to discover what constitutes the experience of ‘baptism in the Holy Spirit’ from a first-person perspective." and warns that the study "does not try to prove or disprove that the phenomenon can be verified as relating to the actual work of the Holy Spirit."

That kind of phenomenological study, combined with post 1970 Communio Approach of doing Catholic theology represented by Henri de Lubac, Hans Urs von Balthasar and Joseph Ratzinger (see chapter 3 of Tracey Rowland's book) is a scholarly model that I find both appealing and responsible: level headed integration of authentic tradition and subjective experience in all cylinders (reason, emotion, desire, will, affection, virtues, etc.)

C.S. Lewis also did similar integration, combining pre-Reformation and possibly pre-Medieval philosophy + theology with modern thought and sensibilities, which is one reason why he is still relevant today.
