Jim Blackburn, “Was the Early Church ‘Catholic’ or Just ‘Christian’?”:

Some might claim that Ignatius intended to use the term “Catholic Church” not as a proper name for the Church, but only as a general reference to the larger assembly of Christians. If so, then the universal assembly had no proper name yet, but “Catholic Church” continued in use until it became the proper name of the one church that Christ built on Peter and his successors.

… Given the unbroken chain of succession at Antioch—from Peter (sent by Christ) to Evodius to Ignatius—if any Christian today wishes to identify with the biblical Christians of the first century mentioned in Acts 11, it follows quite logically that he must also identify with those same Christians’ universal assembly: the Catholic Church.

Thomas Hopko, “The One True Church”:

And here we would definitely say the Church that we say we believe in is the Eastern Orthodox Church. It’s not the Roman Catholic Church. It’s not an Oriental Orthodox Church. It’s not one of the Protestant churches. It’s not the Anglican Church. …

The Church has what I used to call when I used to teach dogmatic theology, it’s got its “authoritative witnesses.” There are witnesses, testimonies, to this truth, the first of which is the holy Scripture and the Bible itself. And this is our faith, and what we would say is, “Yes, indeed, we think that only this Church holds it completely, truly, fully, and rightly.”

John MacArthur, “The Manhattan Declaration”:

Instead of acknowledging the true depth of our differences, the implicit assumption (from the start of the document until its final paragraph) is that Roman Catholics, Eastern Orthodox, Protestant Evangelicals and others all share a common faith in and a common commitment to the gospel’s essential claims. The document repeatedly employs expressions like “we [and] our fellow believers”; “As Christians, we . . .”; and “we claim the heritage of . . . Christians.” That seriously muddles the lines of demarcation between authentic biblical Christianity and various apostate traditions.
