Q. 1. I noticed that different religions use the word "Catholic" in the name of their religion. I thought there was only one Catholic Church. Can you explain what is going on?
A. 1. First of all, it is important to know what the word "Catholic" means. The word catholic has it Latin origin from the word "catholicus" and the French origin "catholique." The Latin and French words originate from the Greek adjective "katholikos", meaning "universal". So when we speak of the "Catholic Church," we mean the "Universal Church."
The word Catholic was first used to describe the Christian Church in the early 2nd century to emphasize its universal scope.
Nowadays, many Protestants sometimes use the term "catholic church" to refer broadly to the Christian Church and all believers in Jesus Christ across the world and the ages, regardless of denominational affiliation. To distinguish them from the Mother Church, the Roman Catholic Church of Rome, when reference is made to the Catholic Church that is associated with the Vatican and the Pope, a capital "C" is used in the word Catholic." Many deceptive small churches will use the word "catholic" in the incorporation of their churches to give the impression that they are associated with the Roman Catholic Church of Rome. They claim to be faithful to the Roman Catholic Church, the Pope, the Magisterium, all of the Church teachings, and will go to extreme to prove that they enjoy apostolic succession by providing a list of who consecrated who, century after century. The purpose of such deception is to draw members of the Roman Catholic Church to their churches.
None of those churches are associated with the Roman Catholic Church. None of them are "a Rite within a Rite" as they claim. There is no such thing as a Rite within a Rite. There is a number of Rites that are in communion with Rome, but these Rites are not a Rite within the Roman Catholic Rite. They are stand alone Rites in themselves that are recognized by the Catholic Church as being in communion with Rome because their teachings are no different than the teachings of the Roman Catholic Church.
The false catholic churches are known, within a few years of their birth, by their teachings that contradict the Roman Catholic Church such as in the matters of women priests, women bishops, ordination of women, gay marriage, supporting divorce, supporting abortion, etc... The leaders of those churches are people pleasers, or as one could say, copy cats of the many Protestant churches that had similar reasons for leaving the One, Holy, Catholic and Apostolic Church that was founded by Jesus Christ.
