Loisy was of a poor family and raised in a rural environ. His first encounter with other seminarians was a shock: he was snubbed and his devotional intellect was ridiculed. He despised mediocrity and intellectuals of his time. He gave them a taste of what he was capable in the intellectual field where he was far superior to all of them. His arrogance and his intellectual position did not warrant him any promotion in the church. He grew ever more more resentful and transferred his hostility toward the Vatican. He might as well have said Vatican instead of church but he was too smart for that.
He may have been criticizing the Catholic Church. Loisy was a Catholic but was excommunicated because of his teaching. He may have been showing disappointment in that Jesus proclaimed the Kingdom of God but that hasn't arrive we only have the church.
Jesus's teachings were written down in the bible through a secondary source, and the church tries to interpret that. SOmetimes teh church doesn't work as well as Jesus, or gets wrong information, becuase they or the writers of the bible are human.
He preached of the coming of a new kingdom. They thought he was possibly planing a rebellion but the kingdom he preached was not a earthly one but in the hearts of men.
He preached the core message of Jesus - the Kingdom of God.
By using other people like pastors and priests that preaching the word of God
that is not a very good question. how, he is gods son, and they fished for food.
Almost all the Reformers preached this doctrine - I can't think of any that taught that the Pope was the head of the church. Martin Luther and John Calvin would be the two most prominent of the group.
He preached
The reign of God means his own kingdom in heaven and his kingdom on earth the church.
I guess it depends on what you consider to be preaching. You might say that he preached to Nicodemus in John 3, or to the Samaritan woman in John 4. But, the earliest that it was written that Jesus preached the gospel was in Mark 1 saying, "The kingdom of God is near. Repent and believe the good news!"
Well The Bible said that while he was on Earth that he preached the goodnews of the kingdom Proclaming it to others. And he did not stop there he actually told his followers to do the same..
Jesus is speaking of the spiritual church, it lives within us. Not of sand, its the spirit of faith in him. And not of this earth.
