That is how membership in an organization works. If you fail to believe as they mandate, then you ain’t part of that group.
Rome mandates that you believe in Mary’s immaculate conception, her assumption, bodily into Heaven as well as her receiving and answering prayers.
All of which is heresy.
You are all over the place. Privation revelation you do not have to believe. Stop accusing like you know what your talking about. Stop acting like the accuser of the brethren.
