The Early Church was the Catholic Church

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