Catholics as Just Another Denomination

Mark Horne says:

But what if Roman Catholics are sectarians dreaming they constitute the historic and perpetual center of the identity of the Church?

What if the real Catholic Church is simply continuing on and the Roman Catholic Church is pretending that it is not lacking that full communion because it has created without warrant autistic conditions for fellowship?

Evangelicals have many issues to work on as they continue through history. But there is nothing to rejoin. If the Roman Catholic Church and another denomination join and receive, then that is simply two denominations uniting together. And if they join and receive under the shared assumption that the Roman Catholic Church is some kind of perpetual “center” that all others are “peripheral” to and must come “back” to, then all that would mean is that the Christian people of the other denomination have become persuaded of sectarian superstitions.
