He didn’t read the fine print.
The New Testament is the fine print. It includes anything and everything one must know in order to secure one’s heavenly eternity. It includes primarily the unabridged original teachings of the Lord Jesus. It also includes the first Christian history book explaining in full detail exactly what it means to be a real Christian by seeing Real Christianity in action. The New Testament includes as well several preserved letters of correspondence and teaching explaining in great detail the actual teachings of original first century Christianity, most of which were written by Paul the apostle, who was also the best teacher of the early Christian Community.
The early believers paid close attention to the Lord’s teachings. In their mature state they followed them to the nth degree. But this did not make them legalistic like the later dogmatic DAs of Unreal Christianity who, like the Pharisees, loved legalism and forced indoctrination. They majored on the letter (though they didn’t follow it) but disdained and rejected the Spirit. Paul said this:
Our adequacy is from God, who also made us adequate as servants of a new covenant, not of the letter but of the Spirit; for the letter kills, but the Spirit gives life. [2Corinthians 3:5-6]
Those who major on the letter refused to be filled with the Spirit as per the Lord’s command. They will not walk in the Spirit, teach the Spirit, or be empowered by the Spirit. Consequently they walk around like religious zombies in new suits while deluding the world into following the dead faux forms of Christianity which the world is deceived into believing are the real thing. They also work very hard at attempting to make the real thing appear illegitimate.
Some people, however, can see right through religious camouflage. Apparently, most people cannot. Thus, most Christians in the world do not follow the Lord Jesus; they follow their own pastors, ministers, reverends, denominational hierarchies, and etc. The more of a following the substitutes get the more powerful they become and the more easy it becomes to spout their false Christian teachings.
SO WE ARE WHAT WE ARE WHY?
There are a few people, and only a few, who manage to discover the roots of their particular denomination. If they remain loyal to their denomination that’s as far as they go. If one is a Protestant, that is, a religious descendant of those who fiercely protested against the Roman Catholics, his roots go back about five hundred years at the most. If one is Catholic, his roots go back to Constantine in the early fourth century. That’s about seventeen hundred years ago. Of course, the Lord Jesus walked the earth two thousand years ago. Wouldn’t it be smart to just keep going back until arriving at the source?
“I have come in My Father’s name, and you do not receive Me; if another comes in his own name, you will receive him. How can you believe, when you receive glory from one another and you do not seek the glory that is from the one and only God?” [John 5:43-44] 
Of course, the vast majority of Protestants and Catholics have absolutely no idea of their actual denominational roots, nor do they care to put any effort into discovering them. Denominational lifers are what they are for various reasons, none of which has anything to do with actually following the Lord Jesus. Why? Because when one actually begins following the Lord Jesus one will intently read all of His teachings and then begin studying His teachings in-depth. When one does this he will find discrepancies between the Lord’s teachings and those of his church or denomination. He will then seek answers for why this is so. His innocent queries will inevitably lead to the leadership. The leadership will then downplay such questions and attempt to further circle the wagons around the straying sheep in an effort to get him back into the denominational corral. This often works. Those who succumb are doomed to being longtime members of a mere religious club who care more for social inclusiveness rather than the Lord’s truth.
Though they start out great following the early truth trail they get cut off at the pass by the religious chucklehead posse.
They then become denominational Christians in which their own denominational teachings always trump the pure teachings of the Lord. Whenever questions arise they never ask “What did Jesus teach?” Instead, they ask, “What does my church teach?” Or “What does the Pope teach? Or Martin Luther, or John Calvin, or John Wesley, or Fatboy, or Smiley. Or “What does my own pastor teach?”
Of course, all of these people are mere men but judging by their fawners they are worshipped as deities. They are never questioned. Questioning one’s pastor is the new unforgiveable sin. It only works in that tiny location, however. When you walk away and shake the dust off your feet you get to be “saved again” and discover the Lord still loves you. You also rediscover cool things like eyesight and liberty and sunshine and places where seldom is heard a discouraging word.
For a New Testament illustration regarding what happens to people who actually question the leadership or particular church doctrines, there is that which happened to the Lord and pretty much all of His early followers: If one was a member of a local synagogue and everyone there did everything they were told to do by the leadership and believed everything they were supposed to believe, then all parties, especially the leadership, were all smiles. It was a quasi-contented and quiet place though there was likely a massive cloud of fear just under the surface. All the good guys—the no power or influence members who desired truth and love—were scared spitless to speak or act or move in any such way which may be rendered religiously incorrect because they knew their entire lives were built on being members in good standing. And that meant following the controllers 100%. There was no independence of thought or seeking of truth. There was certainly no liberty in the Spirit. There was only a sad and spineless kowtowing to “the leadership.”
When one stepped out of line, those beautiful contented costumed clergy boys were suddenly transformed into stark raving mad lunatics who wanted to abuse, maim, and kill. They always had rocks very handy at their disposal.
Does this sound familiar? Because it also accurately describes roughly 90% of Christian “churches.” It used to be that they would disfellowship a person in a nano second but seeing the error of their ways and that it too easily revealed themselves as the Christian Pharisees they were, they reverted to the tried and true Silently Disparage, Gossip About, Reject From Fellowship and Communication, and Treat Indifferently Method. This works just as well and allows the good members thereof to practice world class Holier-Than-Thou smugness. You know, just like the Lord did.
SOMETIMES, TRUTH IS SO INCONVENIENT
The reason so many of these kinds of Christians are so apathetic toward the Lord’s teachings is because it doesn’t matter anyway. They are all told what to believe. They can only legally believe what they are told. If they divert from that they bump up against the edges of their party boundaries. Many therefore refuse even an attempt to seek further Biblical truth because they may inconveniently discover greatly discomforting facts which depreciate the investment in their chosen religious culture. This could in turn cause a weakening of one’s personal foundation and social standing. What then?
