请问： 周三早上梵蒂冈圣彼得大教堂是否正常开

教皇并不在教堂内接见信众。
参见梵蒂冈圣彼得大教堂网页http://www.stpetersbasilica.info/touristinfo.htm#restrooms，周三10点，教皇会在教堂广场或其侧的保罗六世大厅接见信众（需预先取票，但好像并不难），因此无碍大教堂的开放：
Seeing the Pope
On Sundays at noon, the pope usually (if he's in town) appears at the second window from the right of the Apostolic Palace, to pray the Angelus and bless the crowd in the Square. Benedict XVI has continued this tradition, no ticket required.
Otherwise, you can attend the Wednesday 10:00am General Audience held in St Peter's Square. In winter, or bad weather, the audience is held in the Paul VI Hall accessed just to the left of the Square (Sant' Uffico gate). Tickets are required for the Audience, but are easily obtained. See Papal Event Tickets
