I think you’ll find it has diminished rather than spread, and in fact traditionalism seems to have taken hold and notably also amongst young people.
Remember that Jesus said that the gates of hell will not prevail against the Church, so do not fear for the Church though we must continue to work, witness, and pray as good Sacramental Catholics.
What I would promote and what is most meaningful spiritual focus for me is the Sacraments and a sacramental life and in living the commandments of love.…I’m just illuminating the fact that it (the gifts of the Spirit including tongues) is a matter that goes back to the early Church. I know the arguments pro and against but don’t have any wish to engage. God will lead and draw each of us to Him according to His divine will. And God will witness through each of us according to His divine will, in whatever way He chooses. We trust in His mercy and His leading.
Actually the charisms are traditional in that their origins are found in the Bible, the New testament, and in the early Church!
In the early Church…
"And they were all filled with the Holy Spirit and began to speak with other tongues, as the Spirit was giving them utterance." Acts of the Apostles chapter 2 verse 4
"Follow the way of love and eagerly desire gifts of the Spirit, especially prophecy. 2 For anyone who speaks in a tongue does not speak to people but to God. Indeed, no one understands them; they utter mysteries by the Spirit."1 Corinthians 14 verses 1-2
1Corinthians 14:22 describes tongues as a “sign to unbelievers.”
1**" Now about the gifts of the Spirit, brothers and sisters, I do not want you to be uninformed. …
**4 There are different kinds of gifts, but the same Spirit distributes them. 5 There are different kinds of service, but the same Lord. 6 There are different kinds of working, but in all of them and in everyone it is the same God at work.
7 Now to each one the manifestation of the Spirit is given for the common good. 8 To one there is given through the Spirit a message of wisdom, to another a message of knowledge by means of the same Spirit, 9 to another faith by the same Spirit, to another gifts of healing by that one Spirit, 10 to another miraculous powers, to another prophecy, to another distinguishing between spirits, to another speaking in different kinds of tongues,[a] and to still another the interpretation of tongues.11 All these are the work of one and the same Spirit, and he distributes them to each one, just as he determines." 1 Corinthians 12 verses1, 4-11****
Saint Paul also wrote:
**If I speak with the tongues of men and of angels,
but do not have LOVE,
I have become a noisy gong or a clanging cymbal.
If I have the gift of prophecy and can fathom all mysteries and all knowledge,
and if I have a faith that can move mountains,
but have not LOVE,
I am nothing.**1 Corinthians 13:1-2
Well Answered I don’t think this is your own wisdom it is divine. For we cannot understand the way of GOD. Even the Apostles Of JESUS who ate and drank with the Master could not understand these foolishness as it were before Man, But in our own Wisdom we are rendered foolish before THE IFINITE WISDOM!
For many of us who still posit that ‘until we understand it we don’t believe it’ I ask how many of the things or ways of GOD can we clearly explain without reverting to the scriptures which in itself is not written in plain languages. JESUS Originated Tongues, benevolently and freely gave it to the church as He promised. If we lack understanding lets study HIS word.
