They say that there are three branches of Christianity
Catholicism
Protestantism
Eastern Orthodoxy
My question is where do you put:
Palmarian Catholic Church
German “Old Catholics”
The followers of “Pope Gregory XVII” aka Jean-Gaston Tremblay
The followers of “Pope Peter II” aka Chester Olszewski??
Hope someone can clarify this.

This is known as the “branch theory”, or “branch heresy”. This error originated with the Anglican Church in the mid 19th century who thought that the Church was divided, and said we should begin to work for Christian unity.
That error implies a false understanding of the Church, which can never be divided. Groups may split from the Church, such as the Anglicans or Protestants, but this will not effect the unity of the one true Church in any way. When they split from the Church, they cut themselves off from the Church, but the Church itself remains perfectly united.
When the Anglicans began to seek this false idea Christian unity (where the goups “unite” while remaining in separate groups), the Holy Office responded as follows:
"Therefore the Sacred Congregation [of the Holy Office] deeply regrets that it has happened to you who think that those Christian bodies which vaunt themselves as having an inheritance of the priesthood and the Catholic name,
although cut off and separated from the Apostolic See of Peter, belong as parts to the true Church of Jesus Christ. There is no opinion which is more at variance with the genuine notion of the Catholic Church. For the Catholic Church…is that which, built upon a single Rock, rises up into one coherent body and is held together by unity of faith and charity" (The Holy Office, under Pius IX, November 8, 1865).
The following are a few other quotes of interest:
Pope Leo XIII said: "Jesus Christ never conceived of nor instituted a Church formed of many communities which were brought together by certain general traits - but which would be distinct one from another and not bound together among themselves by ties which make the Church one and indivisible - since we clearly profess in the Creed of our Faith: " ‘I believe in one…Church.’ " (Satis Cognitum)
Pope Pius XI said: “It is absurd and ridiculous to say that the Mystical Body can be formed out of separated and disjunct members. … It is to depart from divine truth to imagine a Church which one can neither see nor touch, which would be nothing more than spiritual in which numerous Christian communities would be united by an invisible bond, even though they are divided in faith.” (Mortalium Animos)
The best enclical to read in order to obtain a proper understanding of the unity of the Church is Satis Cognitum, of Pope Leo XIII, which can be found here
