Which branch of Christianity does Pope lead 1-protestant 2-Orthodox 3-Lutheran church 4-Roman Catholic?

Answer 1

Roman Catholic Answer4) the Catholic Church is lead by the Pope in Rome. There are some Orthodox Churches who call their leader a "pope", but the Pope is known throughout the world as the Bishop of Rome. Please note that your question is wrong, as there are no "branches" in Christianity. Christianity consists in the Catholic Churches united to the Pope in Rome. To a lesser extent one could consider Christians any who have been validly baptized and profess the Nicene Creed in it's classical interpretation, all other schismatics, protestants, and other heresies are just that, not "branches".

Answer

Not arguing with the above answerer but the church currently accepts all those baptised in the name of the father, son and Holy Spirit as Christan though their churches are not always thus recognised. This is why the rite of election is as it is and why the RCIA is how it is, with candidates and catechumens. Pope John Paul II specifically on many occasions have referred to the Orthodox Church as Christan, as noted in the celebrations of the jubilee year.

Not to be contrary, but the Roman Catholic Church never has had a monopoly on deciding who is "Christian" and who is not. That is, it is not up to the Roman Catholic Church to define what is, or is not, Christian. Christianity is a general religion, with the accepted world-wide definition being of one who believes in the divinity of Jesus Christ and follows the teachings of the New Testament.

So, there are indeed "branches" of Christianity, although the term "sect" or "faction" is more accurate, and the official term is "denomination". The RCC is the largest sect of Christianity, but not even the majority of Christians (about 1/3) are RC.

Also, back to the original question, there (a) is no single Protestant faith - Protestants are of a large variety of individual denominations, loosely grouped together by some basic agreed-upon tenets, but not organized together in any way, (b) there is no "Lutheran Church", the Lutheran faith has no centralized hierarchy, and, thus, to speak of one "Lutheran Church" is false, (c) the Lutheran faith is part of the Protestant movement (in fact, one of the two original Protestant faiths), and (d) Orthodox Christianity is in fact several denominations (Eastern Orthodox, Oriental Orthodox, and Eastern Christianity).

So, of the four original choices, only the Roman Catholic faith is a single entity. Perhaps it is fortuitous that the answer is that the Pope leads the Roman Catholic Church.
