Until the 11th Century? Not so my friend. The Fathers of the early One Universal Christian Church in the early centuries believed in this doctrine and also of praying for the dearly departed.
First, the article said "as it is known in the RCC today," which is accurate. I also pointed out (as it did), that elements of Purgatory were found in paganism before Christianity existed. Your following quoted do the same thing. They show that the ECF believed in a pagan doctrine invented by a pagan religion and then absorbed into their brand of "Christianity" unknown in Biblical Christianity today as well as unknown in the Bible--a foreign doctrine traceable to paganism not the Bible.
St. Augustine in the year 421 said this: "That there should be some fire even after this life is not incredible, and it can be inquired into and either be discovered or left hidden whether some of the faithful may be saved, some more slowly and some more quickly in the greater or lesser degree in which they loved the good things that perish, through a certain purgatorial fire"
So what? His vain philosophy is no match for the Bible. This is where sola scriptura trumps man's vain philosophy every time.
Mark 7:7 Howbeit in vain do they worship me, teaching for doctrines the commandments of men.
--This is what the RCC is guilty of. The worship if vain. The teach the commandments of God rather than the Word of God, thus their hatred of sola scriptura.
Ephesians 5:6 Let no man deceive you with vain words: for because of these things cometh the wrath of God upon the children of disobedience.
--See the contrast. The RCC comes with deception teaching vain words.
I come with the Bible teaching sola scriptura, for the Bible is my final authority.
Colossians 2:8 Beware lest any man spoil you through philosophy and vain deceit, after the tradition of men, after the rudiments of the world, and not after Christ.
--The philosophy of Augustine and others you quote have taught philosophy and vain deceit after the tradition of me.
I teach Christ through His Word. That is sola scriptura.
1 Timothy 1:6 From which some having swerved have turned aside unto vain jangling;
--This describes the RCC and its founders.
The very next verse continues:
1 Timothy 1:7 Desiring to be teachers of the law; understanding neither what they say, nor whereof they affirm.
--But they don't know the Word of God. Since they teach the commandments of men and vain traditions they are simply false teachers leading people astray. They do not understand what they say nor whereof they affirm. Any person in the RCC should leave immediately!
1 Timothy 6:20 O Timothy, keep that which is committed to thy trust, avoiding profane and vain babblings, and oppositions of science falsely so called:
--Paul told Timothy to keep or remember always those things that he had taught him (the Word of God), but avoid the vain babblings (the teachings of the RCC as they are today). The expression reminds me of the little homilies I used to hear in the RCC.
2 Timothy 2:16 But shun profane and vain babblings: for they will increase unto more ungodliness.
--Paul doesn't stop. He keeps on warning Timothy to shun, not to listen to these vain babblings about Purgatory and other RCC demonic doctrine. They will increase more and more he says prophetically. And if one looks at the RCC today, Paul was absolutely correct!
And Gregory of Nissa wrote in the year 382: "If a man distinguish in himself what is peculiarly human from that which is irrational, and if he be on the watch for a life of greater urbanity for himself, in this present life he will purify himself of any evil contracted, overcoming the irrational by reason. If he has inclined to the irrational pressure of the passions, using for the passions the cooperating hide of things irrational, he may afterward in a quite different manner be very much interested in what is better, when, after his departure out of the body, he gains knowledge of the difference between virtue and vice and finds that he is not able to partake of divinity until he has been purged of the filthy contagion in his soul by the purifying fire"
Nothing here is found in the Bible. It is wishful thinking, the origin of which is found in paganism.
He said:
"
If a man distinguish in himself what is peculiarly human from that which is irrational, and if he be on the watch for a life of greater urbanity for himself,..."
This is an expression of salvation by works found outside of salvation by grace through faith in Christ. He has no concept here that salvation is in Christ. It is heresy.
And St. John Chrysostom: "Let us help and commemorate them. If Job’s sons were purified by their father’s sacrifice [Job 1:5], why would we doubt that our offerings for the dead bring them some consolation? Let us not hesitate to help those who have died and to offer our prayers for them".
Offerings for the dead is necromancy. Necromancy is heresy and those that practiced it were put to death.
Deu 18:10 There shall not be found among you any one that maketh his son or his daughter to pass through the fire, or that useth divination, or an observer of times, or an enchanter, or a witch,
Deu 18:11 Or a charmer, or a consulter with familiar spirits, or a wizard,
or a necromancer.
--Such were put to death.
And then we have Tertullian who wrote: "We offer sacrifices for the dead on their birthday anniversaries [the date of death—birth into eternal life]".
Just because these ECF say it, do it, practice it, doesn't make it right. It was wrong. In the OT they were put to death as the practice was condemned. They should have known better.
"A woman, after the death of her husband . . . prays for his soul and asks that he may, while waiting, find rest; and that he may share in the first resurrection. And each year, on the anniversary of his death, she offers the sacrifice".
And you think this pagan practice makes it right? It is paganism. It is not Christianity. It is practiced in Shintoism and Hinduism. Ask John of Japan, a missionary to Japan.
You constantly go back to paganism. Don't you realize that it was Christianity that supplanted paganism in all manner of ways? I previously mentioned the pagan religion of Mithraism, a way according to Gerald Berry who wrote in the book Religions of the World in which he said: "Both Mithras and Christ were described variously as 'the Way,' 'the Truth,' 'the Light,' 'the Life,' 'the Word,' 'the Son of God,' 'the Good Shepherd.' The Christian litany to Jesus could easily be an allegorical litany to the sun-god. Mithras is often represented as carrying a lamb on his shoulders, just as Jesus is. Midnight services were found in both religions. The virgin mother...was easily merged with the virgin mother Mary. Petra, the sacred rock of Mithraism, became Peter, the foundation of the Christian Church."
Paganism still exists. Google it. The sad thing is that Catholicism has incorporated these pagan practices into their own liturgy and practices. It is paganized Christianity. Thus it is not Christianity at all but simply another pagan religion. Paul admonishes all to separate themselves from such a religion (2Cor.6:14-17).
See what I mean? It's all about the new true religion of God supplanting all the religions that existed before - and guess what, you as a believer you are part of it because of it's long history. There is nothing to be ashamed of here with the natural progression of man's religious thought process.
We follow the Bible. You have followed a religion of paganism. The facts presented are true and cannot be refuted. Demonic doctrines such as Purgatory cannot be found in the Bible, only in pagan religions quoted by ECF leaders with no scriptural background.
