It is an exaggeration. If you look at it, it shows 242 Roman Catholic denominations. This is because the same church in different countries are counted as separate even though they have the same doctrines. This is done with Protestant churches as well. And it includes non-denominational and independents as if each was a separate denomination, although Church x in Boston may have the same teachings as Church y in New York, including the teachings that each congregation is to be independent.
There are not 242 Roman Catholic denominations. There is only one Catholic Church. The Catholic Church is not a denomination.
The marks of the true Church are that she is
one,
holy, **Catholic **and
apostolic. These marks are only to be found in the Roman Catholic Church.
She is
one, because she is united in faith under her visible head. If you want to find the Catholic Church, look for Peter. All Catholics look to him and his successors as the Vicar of Christ on earth. Protestants as a whole have no head, even if some denominations have a head. (The Anglican Communion has the Archbishop of Canterbury and the Queen of England, but they have proven powerless to prevent rifts within the Communion.) Protestants are also not united in faith, but are forever splintering into new sects based on disagreements with doctrine or leadership. This has been going on ever since the days of Martin Luther. In view of that state of affairs, it would be surprising if there were
only 30,000 Protestant denominations.
She is
holy, because she was founded by Jesus Christ. The Protestant denominations came along 1,500 years (or more) too late to have been founded by Jesus Christ.
She is
Catholic, because she is universal. Protestant denominations are not universal. Many, like the Anglican Communion, are characterized by nationalism or regionalism. In fact, the only universal characteristic of all Protestant communions is the belief that one shouldn’t be Catholic.
She is
apostolic, because she has her faith and teachings directly from the Apostles, who had them directly from Jesus Christ. Also, all her bishops are direct successors of the Apostles, and all her priests have been ordained by these apostolic successors. The Protestant denominations abolished the priesthood, and cut themselves off from union with Peter, so their ministers do not relate back to the Apostles.
In short, you can’t lump the Catholic Church in with Protestant denominations. There is no equivalency. What is true of the Protestant denominations is not true of the Catholic Church, so that one can’t dismiss the claims of the Catholic Church as readily as one can dismiss those of any Protestant denomination. (And every Protestant must deny the claims of many denominations, since, at any given moment, he chooses one over all the others.)
