Catholic doctrine is not apostolic. So while they may see a centuries long connected chain, it is a connected history of apostasy. The OP's pervious posts defended the Trinity, the veneration of Mary and other such nonsense that all derive from pagan worship. The Catholic church's history of murder and repine - something that continues - shows it to be anything but Christian. It is Christian in name only.
The past century Witnessed the kidnapping and murder of a young woman, a resident of Vatican City; the concordant with Hitler; the compromise of the Catholic Centralist party in Nazi Germany; the hiding of war criminals, financial 'mismanagement'; interference in and threats to Central American states; priestly support for the Argentinian dictatorship; murders and rapes in Catholic run Canadian schools for indigenous children. None of this is Christ - Like behavior. And none of it is new. And similar things continue. Yet, the OP thinks he's part of and defending the one true church. That's deranged thinking.
