When the Catholic Church was founded . .
For the first 1000 years after Christ, there was only the One, Holy, Catholic, and Apostolic Church of Jesus Christ. In 1054, the Bishop of Rome excommunicated the Bishop of Constantinople who promptly returned the favor.
The
Roman Catholic denomination and the
Easter Orthodox denominations were both founded in 1054.
In 1522, a German monk nailed his 95 Theses to the church door in Wittenberg, and Western Christendom fragmented into where we are today.
