The Early Church was the Catholic Church

When it comes to the history of Christianity, the Catholic Church makes a bold claim: that the earliest Christians were Catholics, and that their beliefs and practices have been carried on unbroken all the way to the present-day Church. But the Last Supper was a long time ago, and Protestants have been attacking Catholic claims about Christianity's historic origins, traditions, and practices for hundreds of years. They would rather believe that the earliest, "purest" Church shared far more in common with their own congregations and doctrines.
