Saint Thomas, thanks for the invitation “home,” but we Christians will stay with Christ.
We don’t worship or “venerate” Martin Luther, so many of us will listen to arguments that he might have left out some books that should be in the Bible.
We Christians assembled the Bible (there were no “Protestants” back then, remember?) and then much later there was a split.
Who left Christ? Not the Christians. Maybe for a time it was those who started to worship a human organization rather than Christ.
The Church is not an organization rather it is the Body of Christ. Those who depart from His body do indeed form a mere human organization sad to say.
