Or, rather was it: so-called 'Christianity'?
Remember Luke wrote us at Acts [20:29,30] that after the first century ended there would be wolf-like clergy that would not spare the flock. -2 Thess 2:7,10.
Jesus gave the illustration of the Wheat [genuine] and the Weeds [tares/false] Christians would both grow together until the harvest time of separation by Christ at his 'glory' [Matt 25:32]
So true or genuine Christianity does not destroy the real Jesus.
Jesus foretold in the 7th chapter of Matthew that 'many' would come in his name but prove false. That does not make the real Jesus destroyed, but rather proves Jesus words have truly come to pass.
Paul says that there would come those who would preach a different Jesus than the one taught by the apostles, and we read in the 1st letter of John 4: 1-3; My dear friends, do not believe all who claim to have the spirit, (My words are spirit) but test them to find out if the spirit they have comes from God. For many false prophets have gone out everywhere. This is how you will be able to know if it is Gods spirit/word: anyone who acknowledges that Jesus came as a human being has the spirit who comes from God. But anyone who denies this about Jesus, does not have the spirit from God. The spirit that he has is from the enemy of the anointed one, the Anti-christ etc.
2nd letter of John verses 7-10; Many deceivers have gone out all over the world, people who do not acknowledge that Jesus came as a human being. Such a person is a deceiver and an enemy of Christ.
It was these deceivers, supported by the non-christian King Constantine, who established the false universal church in 325 AD, that preached a totally different Jesus as to the man the was born of human parents as verified by the scriptures; and it was those deceivers who attempted to change the prophecy in Isaiah 7: 14; which states that an Almah, (Unmarried woman, ) would be with child ect, into the greatest of all lies, that a virgin conceived and gave birth to a son, who was in fact, According to the teaching of those deceivers, an immortal God, who was supposedly the co-creator of the cosmos, who came down to earth and entered the womb of their so-called Virgin, where his father, with whom he had created the cosmos, created a human like body for him which was not of the seed of Adam, from who every human being is a descendant.
And it is that so-called christianity, that refuses to acknowledge that Jesus came as a human being, which blinds those who seek the Kingdom of God,who are the human brothers of Jesus, who we once knew as a man, who was given divine glory by our saviour God and who is now, incontestably divine; see Acts 3: 13; from even finding the door that leads to eternal life.
