It might, however, be useful to keep in mind if one encounters the sort of person who insists that traditionalists, in order to be part of the Church, must proclaim our loyalty to Vatican II. I am guessing that there are not many of that sort on this forum.
Most people on this forum reject one or more declarations of the Second Vatican Council, yet they still believe that the Conciliar Clowns are true Popes. Unfortunately, if they believe that they are true Popes then they must adhere to all the declarations of Vatican II. This is because the clowns make it a requirement for communion with them and their sect that you acknowledge the Second Vatican Council as a valid General Catholic Council. As such you are automatically bound to the declarations concerning faith and morals. No Catholic can reject a declaration concerning faith and morals from any true Catholic General Council. This is my point.
