....you are willing to submit yourself to and abide by ALL of the teachings of the Church. (see Heb. 13)

Any of the groups that you have posted who do not abide by this, though they may call themselves Catholic,.... are not Catholic.

Those of us who do submit to and obey ALL of the teachings of the Church, are ONE!

There is no Christian group that even resembles our unity outside of the Catholic Church.
