I commend you for being honest, open-minded, and having an interest in exploring Catholicism.
The term ‘Catholic’ is traditionally known to mean universal and that is because the Catholic Church IS universal… no matter what country, state, city, or anywhere else that Catholics are located, we can all celebrate the Mass together within a Catholic Church thru following the teachings of the Magisterium, The Liturgical Calendar, the Sacraments (Baptism, Confirmation, Eucharist, Penance/Reconciliation, Anointing of the Sick, Holy Orders, Matrimony), & other Catholic teachings intertwine. So my (catholic) friend who lives in Kenya or another (catholic) friend of mine who lives in Wisconsin & me who lives in another state- we can discuss the same Readings, Gospel, Psalms, and The Eucharist on any day of the week (by following The Liturgical Calendar- holy days of obligations, feast days, Advent, Lent, Ordinary Time, Easter, Christmas, etc.) because catholic are “one, holy, catholic, and apostolic Church” (The Nicene Creed). Within the Mass, us catholics celebrate the Eucharist (which we believe is Jesus’ Body [also known as the ‘host’, which is bread] & Blood [wine- 1 sip per person to share]~ the Eucharist is the center of the Catholic Church because it is at Mass that we receive Christ to continue nurturing our souls to then spread the selfless love and service to others we meet. As catholics, we are all called to achieve holiness and each one of us has the potential (with Jesus, of course) to become Saints (who are ordinary & imperfect people, just like everyone, that followed God’s Will for their lives by ‘dying of self’- meaning that they lived selfless lives for others out of love for God [check out: Saint Francis of Assisi, Saint Teresa of Calcutta, Saint Augustine of Hippo, Saint Catherine Laboure~ some of my fav Saints], rather than someday to eventually earn our way to Heaven to be with God [who is infinitely perfect, loves everyone unconditionally, etc] in paradise. I’m not a pro at explaining Catholicism, but this is just paraphrased briefly for you.
If you’re interested in diving deeper into Catholicism, I highly recommend:
~joining RCIA (Rite of Christian Initiation of Adults- more like an intro to Catholicism)
~reading Catechism of the Catholic Church (shares what we believe)
~readingA Biblical Walk Through The Mass: Understanding what we Say and Do in the Liturgy by Edward Sri
~reading, praying, & contemplating the Liturgy of the Hours (also known as the Divine Office)
[a shorter version of this is called ‘Christian Prayer’- MP, DP, EP, NP. This is designed more for those of us catholics discerning a religious Vocation as a religious brother/friar, priest, religious sister/nun- but lay people can too].
~watching “Catholicism” documentary dvd set by Fr. Robert Barron
~watching The Passion of the Christ film (2004)
~exploring Catholic Answers website (not just forums), EWTN, chastity.com, Catholic Online (website) to learn about all of the Saints.
~reading about theologians- such as Dr. Scott Hahn, Edward Sri, Matthew Kelly,
~watching YouTube videos of Fr. Mike Schmitz from Ascension Presents (mix of catholic topics) & Catholic Answers Live (Q&A about catholicism- answers from catholic theologians).
*Overall, pray about the idea of you considering to be catholic and invite Christ into your present thoughts, ideas, etc. and let Him reveal to you what His plan is for your life thru it all. He truly knows & loves us more than we truly know & love ourselves inside-out. “Everything’s going to be okay” (Our Lady of the Miraculous Medal, Nov 2014), no matter what. I will pray for you, dear brother-in-Christ or sister-in-Christ.
