Hi,
Mister Emu: A couple of questions for you. When was the Biblical canon codified? When was the Church first called Catholic? Do you find any relevance to the gap between these two dates and the ability to say that the Catholic Church is the product of "Biblical Christianity", instead of the other way around?
***
The bible canon of the Hebrew scriptures list 24 books that were recognized by Christ and the early Christians. It was only from these writings that the inspired writers quoted and introduced them by saying things like "as it was written"to give you the names and dates regarding canonicity of each book goes beyond this discussion.

Mister Emu: When was the Church first called Catholic?
***
Thanks to the fact that we are living in the age of information the dark history of the Catholic church is (much to their chagrin) not hidden.
The Roman Catholic church unofficially came into being in 312 A.D., at the time of the so-called "miraculous conversion" to Christianity of the Roman Emperor Constantine but he still worshiped the sun god. Although Christianity was not made the official religion of the Roman Empire until the edicts of Theodosius I in 380 and 381 A.D., Constantine, from 312 A.D. until his death in 337, was engaged in the process of simultaneously building pagan temples and Christian churches, and was slowly turning over the reins of his pagan priesthood to the Bishop of Rome.

Catholic means:an amalgamation, blending or merging. Following the institutionalization of Catholicism a host of pagan belief and ritual where sanctified by the church. This is in harmony with prophesies foretold by the apostle Paul regarding the apostasy and increase of false teachers creating imitation Christians who would give attention to misleading inspired utterances.e.g.(2Tim 4:3;2Thess 2:2;Mat 13)

Mister Emu: What do you mean by immortal?
The Bible clearly states that the soul exists, at least for an indeterminant amount of time, past the death of the body. It has no "natural" lifespan. What is that, if not immortal? Only God, in his power, can end a soul.
***
Immortality is clearly defined in the bible, as is the ability to murder our fellow man. there is no need for me to redefine these concepts or to seek explanation elsewhere.
Ez 18:4 "the soul that is sinning...will die"
Mat 25: "...these will depart into everlasting cutting-off
the dead are conscious of nothing and are completely inactive/(Ec 9:5,10;Ps 146:4)
The dead are compared to dust.(Ps 22:15)
The same original-language words for "death" or "dying" is applied (in the bible) to humans, animals and plants.(Ex 3:19;9L5;Joh 12:24;Jude 12;Re 16:3.)
In the bible there is only Life or death, death is simply the exact opposite of life (Deut 30:15).
The argument that life continued after death was started by Satan adopted by Pagan religion seeped in Greek philosophies then infiltrated in Christianity through the Catholic church.
Notwithstanding that if the soul did not die the scriptural doctrine of the resurrection would make no sense.
