How Important Are The Differences?

The divisions that exist now are very different than the divisions that existed when I became a Catholic about fifty years ago.  The divisions between Catholics and Protestants are far less important to both sides now, even though they still exist, than they were fifty years ago, because we are facing a common enemy, a culture of death, a society that is becoming increasingly anti-Christian.  When a common enemy threatens, then warring brothers put their civil wars on hold for a while, important as they are.  Like the Irish and the English, who've had a lot of troubles, but fought together and died for each other in the trenches in World War I and again in World War II.
