As you should know, most Christian denominations practice Open Communion -- all are welcome!  The Roman Catholic church as a denomination is a notable exception, but even in the RCc there are many exceptions to the exception!

To which I add that this and other posts which you make here are unreliable as Catholic teaching.  You may not like or care for the current Magisterium, as is pretty obvious, but it IS Catholic!  And that disdain is a likely contributing source of your unreliability in matters Catholic!
