I think it so very critical that we understand the context of the words of Scripture, the events surrounding them, and know we share in the common faith and its development. It can’t always be a burning in the bosom…again, that is more personal and individual and can’t be applied when constructing doctrine and rules for Christ’s universal Church.
About the Great Apostasy…I refer here back to the death of the Last Apostle.
St. John the Evangelist was no compromiser to those took the Lord’s teachings and made them into a different message, a different form, and a different end. St. John would leave the public bath if a known heretic entered, because this individual was leading people astray from the true message of Christ, His salvation and redemption.
Did he give us any warning before his death of the forthcoming apostasy…? I would think he would, especially because he was the apostle that ‘Jesus loved’. John saw from the beginning that the Lord’s message was love, that we are to love God with our whole heart, soul and mind and to love our neighbor as ourselves.
So we must turn then to the last writings of the Evangelist John, the last Apostle who marked the completion of Who Christ Is as the fulfillment and completion of Who God is in His revelation to us.
To appease Mormons about our progression into God, S t. Augustine states that by listening to the Apostles, we as Church are indeed the Body of Christ present to the world. But ours is not one of ruling, but of loving and serving. We can only judge one’s fruits but not one’s soul.
In the final writings of St. John, the referral to the apostasy is in Rev 21, 5-8…first Jesus replaces the Tree of Life with the Forbidden Fruit that was tasted by Adam and Eve in the seduction they were to become as gods…to Christ naming Himself as Alpha and Omega…beginning and end…defining those who inherit eternal life and those – the apostates and sinners who do not…
"The one who sat on the throne said, "Behold, I make all things new.: Then he said, “Write these words down, for they are trustworthy and true.” He said to me, “I am the Alpha and the Omega, the beginning and the end. To the thirsty I will give a gift from the spring of life-giving water. The victor will inherit these gifts, and I shall be His God, and he will be my son. But as for cowards, the unfaithful, the depraved, murderers, the unchaste, sorcerers, idol-worshippers, and deceivers of every sort, their lot is in the burning pool of fire and sulfur, which is the second death.”
In Rev. 22: 14: “Blessed are they who wash their robes so as to have the right to the tree of life and enter the city through its gates. Outside are the dogs, the sorcerers, the unchaste, the murderers, the idol-worshippers, and all who love and practice deceit.”
The Lord admonishes us not to fret over those who do evil…let them continue to be filthy and do bad…but we are to stand firm.
I do not see the successors to the Apostles being cowards, unfaithful, depraved, murderers, unchaste, sorcerers, idol worshippers, and deceivers of every sort. The Apostles would not appoint such to be successors.
Instead, Rev 5: 11-12, St. John the Evangelist envisioned no less the Daily Sacrifice, the atonement for our sins, The Lord as Lamb – symbol of our way in following Jesus --self-emptying The Lamb of God…our Passover Lamb…Who takes away the sins of the world"As my vision continued, I heard the voices of many angels who surrounded the throne and the living creatures and the elders. They were countless in number, thousands and tens of thousands, and they cried out, “Worthy is the Lamb that was slain!”…the fulfillment of the prophecy by Melchizedek of the only perfect sacrifice…Our Lord’s Last Supper a banquet table…Rev 19: 7,9: This is the wedding day of the Lamb…Happy are they who have been invited to the wedding feast of the Lamb!’
The final works of St. John are pointing us to Christ the Alpha and Omega, the Sacrificial Passover Lamb to be sacrificied and witnessed by countless numbers of people…“Happy are those who are called to His supper”…this whole event taking place since ancient times every hour of every day in atonement for our sins that we in the world commit daily.
Finally the reference to St. Paul’s Galatians as a sign of the Great Apostasy to follow does not hold weight as he is giving his farewell speech and he is also warning the faithful of the same–those who commit sorcery, fornication, and all sins against chastity, those who are depraved and lie, and lead others away from God, the idolators, the murderers…these are the apostates.
Thus one cannot say the apostasy began at the death of the last apostle. On contrary the apostle pointed to the living and lasting Be’Kaa, the living Memorial of Jesus Christ in the Mass.
