A thoroughgoingly false statement.
Please. Are you going to tell me that, for example, the physical assumption of Mary can be inferred from the scriptures? Can you point me to a single tradition from the early Apostolic church that states it? Citations, please. How about papal infallibility? Are you aware that it resulted from a church dispute less than 1,000 years ago and that initially the papacy rejected it (until it was decided that it might be convenient on occasion)?
