But if we Prots say...
Collective mind reading is allowed, e.g. Catholicsbelieve ...
...we'll get massive amounts of gnashing and wailing.
It is one thing to quote a CURRENT TEACHING OR ISSUE and discuss it with a Catholic. It is another thing to quote documents from hundreds of years ago which have since been amended, incorrectly interpret them, and discuss erroneous notions about what Catholics believe, without a Catholic in the particular post. We begin with one topic and inevitably PAST Councils, Indulgences, The Spanish Inquisition and the Wiki list of "Bad Popes" comes up.
There are current encyclicals, Vatican II documents, the CCC, the Catholic News Agency and EWTN's website to refer to, where there exist actual current verbatim statements of our beliefs. It beats speculation, misinterpretation, confusion, and flat out erroneous assumptions about what Catholics believe, in some sidebar.
