What is a Catholic Christian?

Answer 1

All Catholics are Christians, but not all Christians are Catholics. Therefore a Catholic Christian would denote a Christian who belongs to a Catholic denomination of Christianity.

A Christian is someone who is a follower of Jesus Christ: one who professes belief in Jesus as Christ or follows a religion based on the life and teachings of Jesus. A Christian is a member of a Christian Church or denomination who might be Catholic, Protestant, Evangelical, Anglican, etc.

Catholicism is a denomination, and is, therefore, a subset of Christianity. A Catholic is a member of any of the Churches regarded as Catholic, especially a Roman Catholic.

Answer 2

A Catholic Christian is technically a redundancy. It only has any real meaning to a protestant as the protestant have redefined the word Christian to include members of "churches" outside of the Church founded by Jesus Christ.

Answer 3

Roman Catholic AnswerA Catholic is the same word for a Christian. Only in the last several centuries has the term "Catholic Christian" been used usually by protestants to denote a Catholic. This has come about because protestants use the word "Christian" to refer to themselves, and many protestants have come to think of Catholics as non-Christians. A very sad state of affairs, that extends all through theology as protestants have redefined many words to mean other things than they originally have meant.

Christian

A name first given to the followers of our Lord at Antioch (Acts xi, 26). Since the rise of Protestantism the name has been used in so many different senses as to have become almost meaningless: it may indicate a Catholic or a Unitarian, or even be applied to an infidel who displays some virtue which is associated with Christ. It may reasonably be applied to the members of all the ancient churches, whether in communion with the Holy See, or not, and to those Protestants who profess, explicitly or implicitly, the Nicaean creed in its traditional interpretation. The Church puts no definite official meaning on the word, as she does on Catholic.

Catholic I. The word is derived from Greek and simply means universal. In combination with the word "church" it essentially merely indicates one of the marks of the Church, and was so used by St. Ignatius at the beginning of the 2nd century; but in the course of history it has come to be the distinguishing epithet of the Church of Christ and his faith: under other circumstances its place might have been taken by "apostolic" or "one." The use of the word in this distinguishing way became current and common in England only from the middle of the 16th century. In some mediaeval translations of the Creed unam sanctam catholicam et apostolicam ecclesiam is rendered "one holy apostolic church general."

ii. A Catholic is any person who, having been baptized, does not adhere to a non-Catholic religion or perform any act with the intention or effect of excluding himself from the Church. A "good Catholic" is one who practises his religion to the best of his ability.
