No, there was only the Church of Jesus Christ
There was no "pope", no priesthood, no mass, no 7 sacraments , no "holy water".. no assumption or immaculate conception..no prayer to saints.. those are all the works of men
Sure there were....Peter was the Pope (titular head of the new church)...Mass was insstituted at the Last Supper....All 7 Sacraments had been instituted by Christ...Holy water is a sacramental and I don't know how it came to be..(irrelevant)....The Assumption and Immaculate Conception, while being facts, had not yet been declared as Dogma but with the assurance of Christ that in such matters they could not err, the Church formally declared them to be part of scripture.
