Oh, I now how you all are united. And his name is Lucifer.
“Who’s “we”? Most protestants claim to belong to one denomination or another.
Sounds as if you do not know how we are united.
None of “you” are united, because outside the (Catholic) Church there is no salvation”.
These are different denominations of doctrinal understandings, not different Christs. And there are non-catholic, non-protestant, non-denominational local assemblies meeting in the Name of Jesus, following His Word, obeying the Great Commission, and of whom I believe are the True Churches of Christ on earth.
Oh, I now how you all are united. And his name is Lucifer.
