Protestants are a small minority.
First they are disorganized amongst at least 10,000 different church-sects.
Second, of the worlds approximately 2,400,000,000 Christians, only about 600,000 are Protestant. 1.8 billion of the worlds 2.4 billion Christians are CATHOLIC Christians - 1.3 billion total Catholics in communion with the Holy See of Rome, plus about 500 million total Eastern, Oriental, and Assyrian Orthodox/Catholic Christians.
So a 25% minority of the worlds Christians belong to one of 10,000 varying and contrary sects.
The 75% vast majority of Christians on Earth belong to one of four different Apostolic, catholic, holy Christian Churches.
Of that 1.8 billion 75% majority, about 1.3 billion are part of the One, Holy, Catholic, and Apostolic orthodox Christian Church - the Latin-Roman Churches, and the various Eastern Catholic Churches centered around peace and communion with the Holy Apostolic See of St. Peter.
The other half a billion Christians in the 75% Apostolic Christian majority are split between basically only two Communions of Churches - the Eastern Orthodox Catholic Christian Church, whos Primacy is in the Holy Apostolic and Ecumenical Patriarchate of Constantinople, the See of St. Andrew, and the Oriental Orthodox Catholic Christian Church, whos Primacy is in the Holy Apostolic See of Sts. Mark and Peter, His Holiness Pope Tawadros II. There is also the Assyrian Apostolic Catholic Churches, whos Primacy resides in the Holy Apostolic See of Sts. Thomas and Bartholomew, the Patriarch of Babylon and the East, currently His Holiness Patriarch Mar Gewargis III (one which calls itself the Ancient Assyrian Church of the East, the other, smaller sect called the Ancient Church of the East) - but these are relatively minor, with less than 1 million total, mostly in the Middle East around Syria and Iraq.
How glorious would it be to see a revived Catholic Church, and all Catholic Christians to be in communion under a Heptarchy:
+The Holy See of Sts. Peter and Paul in Old Rome and the Holy Father Pope Francis
+The Ecumenical Patriarchate and See of St. Andrew in Constantinople, the New Rome, and His All Holiness Ecumenical Patriarch Bartholomew I
+The Holy See of Sts. Mark and Peter in Alexandria, and the Coptic Pope, His Holiness Pope Tawadros II
+The Holy See of St. Peter in Antioch and the Patriarch of Antioch
+The Holy See of Sts. Peter and James in Jerusalem, and the Patriarch of Jerusalem
+The Holy See of Sts. Thomas and Bartholomew in Babylon and the Patriarch of Babylon
+The Holy See of St. Andrew in Moscow, the Patriarchate of Moscow and All Russia, and His Holiness Patriarch Kirill.
What a glorious thought imagining each of these ancient Apostolic seats of Christianity once again dwelling in peace, unity, and full communion and charity. I FERVENTLY pray for that to happen as Christ Himself prayed.
So just remember that - Protestants: a mere 25% minority of the worlds Christians who exist amongst the 99% of Christian sects.
