Well stated Harley. In the History of Christianity by Paul Johnson, he states that Paul was not exactly enthralled with the 'center' party in Jerusalem, nor them with him, and if James was our Lord's brother, imagine the element that adds to the whole thing?
Unfortunately, the politics started too soon after our Saviour's death, but it seems to me everyone had to see that coming, as Christ left a human church as well as a Divine one.
From Schaff's History of Christianity:
"The conversion of Paul marks not only a turning-point in his personal history, but also an important epoch in the history of the apostolic church, and consequently in the history of mankind. It was the most fruitful event since the miracle of Pentecost, and secured the universal victory of Christianity.The transformation of the most dangerous persecutor into the most successful promoter of Christianity is nothing less than a miracle of divine grace. It rests on the greater miracle of the resurrection of Christ. Both are inseparably connected; without the resurrection the conversion would have been impossible, and on the other hand the conversion of such a man and with such results is one of the strongest proofs of the resurrection.
The bold attack of Stephen—the forerunner of Paul—upon the hard, stiff-necked Judaism which had crucified the Messiah, provoked a determined and systematic attempt on the part of the Sanhedrin to crucify Jesus again by destroying his church. In this struggle for life and death Saul the Pharisee, the bravest and strongest of the rising rabbis, was the willing and accepted leader.
After the martyrdom of Stephen and the dispersion of the congregation of Jerusalem, he proceeded to Damascus in suit of the fugitive disciples of Jesus, as a commissioner of the Sanhedrin, a sort of inquisitor-general, with full authority and determination to stamp out the Christian rebellion, and to bring all the apostates he could find, whether they were men or women, in chains to the holy city to be condemned by the chief priests.
Damascus is one of the oldest cities in the world, known in the days of Abraham, and bursts upon the traveller like a vision of paradise amidst a burning and barren wilderness of sand; it is watered by the never-failing rivers Abana and Pharpar (which Naaman of old preferred to all the waters of Israel), and embosomed in luxuriant gardens of flowers and groves of tropical fruit trees; hence glorified by Eastern poets as "the Eye of the Desert."
But a far higher vision than this earthly paradise was in store for Saul as he approached the city. A supernatural light from heaven, brighter than the Syrian sun, suddenly flashed around him at midday, and Jesus of Nazareth, whom he persecuted in his humble disciples, appeared to him in his glory as the exalted Messiah, asking him in the Hebrew tongue: "Shaûl, Shaûl, why persecutest thou Me?363 It was a question both of rebuke and of love, and it melted his heart. He fell prostrate to the ground. He saw and heard, he trembled and obeyed, he believed and rejoiced. As he rose from the earth he saw no man. Like a helpless child, blinded by the dazzling light, he was led to Damascus, and after three days of blindness and fasting he was cured and baptized—not by Peter or James or John, but—by one of the humble disciples whom he had come to destroy. The haughty, self-righteous, intolerant, raging Pharisee was changed into an humble, penitent, grateful, loving servant of Jesus. He threw away self-righteousness, learning, influence, power, prospects, and cast in his lot with a small, despised sect at the risk of his life. If there ever was an honest, unselfish, radical, and effective change of conviction and conduct, it was that of Saul of Tarsus. He became, by a creative act of the Holy Spirit, a "new creature in Christ Jesus."
This tells what I think is the reason for St. Paul's independence and love of freedom. There is not another Christian writer, priest, pastor, rector, vicar, etc. who so joyously imparts the Good News to his congregation. When St. Paul died, decades elapsed and the corralling (necessary or not) of the Faith began, the freedom in Christ, that he so wanted his congregation to keep so close to their breast was lost to exigencies.
As usual that is an excellent analysis. I have always placed the decline around 600AD but on reflecting on your statement, I believe you're right that it started with the death of Paul. The freedom was lost to organizationalism.
