What is Important to Understand About Jesus Christ

What understandings about Jesus Christ were important to His first disciples? We get so caught up in what is the "right" or "orthodox" theology about Him, that we emphasize that instead of what it actually means to be His disciple.
     The primary concern of the first disciples as far as understanding about Jesus Christ after His ascension in particular was heavily practical and tactical. That is, they were concerned about what they had seen, heard, and even handled. They knew Jesus Christ was a flesh and blood human being. They had eaten with Him, camped out with Him, walked with Him from Tyre down to Jerusalem, and everywhere in between. They were adamant that this not be misunderstood. He was real. They touched Him. Smelt Him. Saw Him. Heard Him. They knew Mary was a virgin when she gave birth to Him. How did they know? Because she told them. They also knew that He referred to Himself as the Son of the God, and so did various spiritual beings when they encountered Him. Jesus consistently referred to God as His Father in more than a religious or metaphorical sense. They knew Jesus displayed powers that could only be ascribed to the Divine, and it would not have been lost on them that the powers He displayed the Greeks and Romans would have associated with their own deities. They knew that He had been arrested, tried, crucified under the authority of Pontius Pilate, and that they had physically seen Him alive the third day afterwards, as well as many times in many places over the next forty days until He was taken up into the sky from them on the road east from Jerusalem to Bethany. They also knew that they weren't the only ones to see Him alive after His death. They knew that He had blown on them and given them His holy Breath, and that on Pentecost that Breath had been triggered in a major way causing them to display His powers and personality for everyone to see (I'm pretty sure Caiaphas saw Jesus in Peter's eyes when he accused him of murdering Jesus). They also knew that two apparent men shining like sun reflectors told them that He would return the same way, before disappearing themselves. Aside from this, they remembered what He taught, memorized it and wrote it down.
     None of the teaching they refused to compromise on was speculative, or deduced from logic or Scripture. It was what they themselves had experienced. Even Paul who had come late to the party taught what he himself had been taught by Jesus Christ when he was in the desert before returning to Damascus. Furthermore, Paul in his writings was explicit that those disciples he taught not spend any time on speculations about things none of them had seen or heard, or as he put it "endless genealogies." And he was explicit on those followers of the Way not spending any time trying to keep the Torah, but focusing on submission to and cooperation with the Holy Breath they had all received from Him.
     And this was really it. This was all the teaching about Him which they insisted on, passing on what they themselves had experienced, and adding nothing to it, or taking away anything from it. They were adamant about keeping their story straight and grounded in what they had seen and heard and not letting it get twisted or "spiritualized."
     In other words, as far as they were concerned, you could hold whatever opinions about anything else that you wanted as long as you didn't insist on everyone else holding them as well. Those other opinions just weren't important enough to worry about unless they interfered with the truth about what they had seen and heard. The same was true of whether or not you kept certain feast days, fast days, and so on as long as you submitted to and cooperated with the Breath of Christ.
     In the modern churches, it is these opinions about everything else which we fight about, excommunicate for, and split ourselves into factions over, and the submission to and cooperation with the Breath of Christ is treated as an afterthought, if at all. Unimportant at best. This is why the modern churches don't function correctly, and haven't for a very long time. They have been corrupted and have been decaying from the inside out.
     If we are going to stand as a united body of Christ, that unity first begins with connecting to the Head through submission to and cooperation with the Breath of Christ. And when we connect to the Head who is Jesus Christ, we connect with each other as a unified body. We too need to get our story straight, and focus on what was seen and heard, as well as what we ourselves see and hear. Each person may have their own opinions on what they have neither seen and heard as long as they don't assume prominence over what was, and don't cause factions and disconnections from the Head through fear and anger.
