Welcome to the Forums. I hope you enjoy your time here and I hope you find the answers you are seeking.
Firstly, you should refer to the
Catechism of the Catholic Church if you have any questions about Catholic belief and practice. It is available free online:
vatican.va/archive/catechism/ccc_toc.htm
You should also read the
Compendium of the Catechism of the Catholic Church. This book summarises the information in the Catechism and provides information in a question and answer format. It is easier to understand. This is also fee online:
vatican.va/archive/compendium_ccc/documents/archive_2005_compendium-ccc_en.html
The information you want is available in both of these documents.
I was curious where the Church stands on speaking in tongues.
The Catholic Church acknoweldges the existence of tongues as an extraordinary charism of the Holy Spirit. The Catechism has this to say about the Charisms of the Holy Spirit:
Charisms
799 Whether extraordinary or simple and humble, charisms are graces of the Holy Spirit which directly or indirectly benefit the Church, ordered as they are to her building up, to the good of men, and to the needs of the world.
800 Charisms are to be accepted with gratitude by the person who receives them and by all members of the Church as well. They are a wonderfully rich grace for the apostolic vitality and for the holiness of the entire Body of Christ, provided they really are genuine gifts of the Holy Spirit and are used in full conformity with authentic promptings of this same Spirit, that is, in keeping with charity, the true measure of all charisms.253
801 It is in this sense that discernment of charisms is always necessary. No charism is exempt from being referred and submitted to the Church’s shepherds. "Their office [is] not indeed to extinguish the Spirit, but to test all things and hold fast to what is good,"254 so that all the diverse and complementary charisms work together "for the common good."255
Tongues is a phenomena which helps the Church in her divine mission to preach the Gospel for the salvation of souls. The Pope and the Bishops united with him have the task of deciding whether the gift of tongues is genuinely from God. If the Church has investigated the phenomena and declared it to be truly from the Lord, then the entire faithful receive the charism with joy and thanksgiving. However, these phenomena do not add or take anything away from the teachings of the Church. Christ was the full and complete Revelation of God to man; and there is to be no further revelation of God to man until his glorious return. Although the Church may declare an extraordinary manifestation of the Spirit worthy of belief, the faithful are not required to believe. We are only required to believe in the Sacred Deposit of Faith.
All supernatural phenomena, such as speaking in tongues, is only genuine if it approves or affirms the doctrines of the faith. Nothing from God will contradict the teachings of the Church. No true spirit from God will contradict the Gospel of the Lord. The manifestation of the Spirit will always lead people to Christ and the Church he established.
The Second Ecumenical Council of the Vatican or Vatican II had this to say about the charisms of the Holy Spirit:
“The manifestation of the Spirit is given to everyone for profit”.(115) These charisms, whether they be the more outstanding or the more simple and widely diffused, are to be received with thanksgiving and consolation for they are perfectly suited to and useful for the needs of the Church.
Extraordinary gifts are not to be sought after, nor are the fruits of apostolic labor to be presumptuously expected from their use; but judgment as to their genuinity and proper use belongs to those who are appointed leaders in the Church, to whose special competence it belongs, not indeed to extinguish the Spirit, but to test all things and hold fast to that which is good.
Reference: Lumen Gentium paragraph 12.
Bold is mine.
The Faithful are instructed not to seek extradordinary gifts of the Holy Spirit. Catholics do not try to receive the gift of tongues. We accept tongues as a gift of the Holy Spirit given to those whom he alone chooses. Tongues are only given if they help or aid the Church. Tongues are not used as a magic trick; they are given for the benefit of the entire Church, not of individuals.
I think you will enjoy this article. It fully explains the Catholic position on tongues:
