Catholicism is a sect/denomination of Christianity, it is not of and by itself singularly Christianity.
“Catholicism is a sect/denomination of Christianity, it is not of and by itself singularly Christianity.”
False. The Catholic Church cannot be a sect, nor can it be a “denomination”. Denominations have formed after breaking off from the Catholic Church (e.g. Lutheran groups, Anglican, etc). Christ established ONE Church and that’s the Catholic Church.
