Ya know he was Catholic right?
From Wikipedia: Justin Martyr, also known as Saint Justin (c. 100 – 165 AD), was an early Christian apologist, and is regarded as the foremost interpreter of the theory of the Logos in the 2nd century.[2] He was martyred, alongside some of his students, and is considered a saint by the Roman Catholic Church,[3] the Anglican Church,[4] and the Eastern Orthodox Church.[5]
Of course not...There were no Catholics back then...
The Roman Catholic Church was a part of the Orthodox Church, believing and teaching the same doctrines and Sacred Tradition, until 1054. It was the Roman Catholic Church that broke away from the Orthodox Church. In that year the Patriarch of Rome, or the bishop of Rome, also known as the Pope of Rome broke away from the original Church by making unacceptable claims of authority over the entire Christian Church. Since then, the Roman Catholic Church has added new teachings, which the ancient Christian Church above rejects. One of these is the Doctrine of the Infallibility of the Pope. Not only this doctrine but also other matters of the faith have developed within the Roman Catholic Church which has since has separated both these Churches.
Don't you think it's a little queer that the Orthodox claim the authority for being the first, real church as well as your religion???
Since history shows that your religion didn't have a pope until at least the 6th Century, it's clear that the Orthodox were the originators of your dual religion...So Justin Martyr may have called himself Orthodox but certainly not Catholic...
Besides, the catholic religion is referenced as the universal religion while the (C)atholic (C)urch is an institution...
