Or a failed one.
It is not exempt from that kind of discipline from Jesus, if they really were a true church. But considering the path they’ve taken, they wandered off that path millennia ago.
We are the Church of Jesus Christ; you may consider that a true church or not, given your repudiation of the Nicene Creed and your rejection of the Trinity. It is not up to you to to define God or His institutions.
Lets call a spade a spade. I prefer the term "Excommunicated Catholic" for those who have left and now rail, a jure, against the Church. In the code of Catholic canon law currently in force, there are eight instances when a person may incur excommunication latæ sententiæ. One of these applies, ipso facto, to a number of the anti-catholics who frequent these threads. Apostates from the faith, a heretics, and schismatics have, by their own actions, severed Communion with the saints.
