Why does religion use complicated language?

If religion is defined as man’s pursuit of the knowledge of God, then God is reduced to an academic outcome and, just like any other academic field, religion is fully capable of becoming encumbered with its own vernacular. Almost like ancient Gnosticism, which practiced and promoted the idea of a mystical, special imparted knowledge of God that only a few could know, religion as academic field becomes specialized, with its own words and phrases that quickly distinguish the learned from the not-so-much. The fact is, Jesus Christ did not come to earth to establish a religion. He came to point the way to a relationship between His Father and His creation. Jesus himself was very critical of those who practiced religion but totally missed the relationship—particularly to the Pharisees and other religious leaders of His day. In maybe the clearest statement that focused on the difference between the religious practices of the day and what He had in mind, Jesus said, “Isaiah was right when he prophesied about you hypocrites; as it is written: ‘THESE PEOPLE HONOR ME WITH THEIR LIPS, BUT THEIR HEARTS ARE FAR FROM ME. THEY WORSHIP ME IN VAIN; THEIR TEACHINGS ARE BUT RULES TAUGHT BY MEN.’ You have let go of the commands of God and are holding on to the traditions of men”—Jesus Christ, Mark 7:6-8 (quoting Isaiah 29:13). Later on, in Jerusalem, Jesus made one of His strongest denunciations of the religious establishment: Woe to you, teachers of the law and Pharisees, you hypocrites! You give a tenth of your spices—mint, dill and cummin. But you have neglected the more important matters of the law—justice, mercy and faithfulness. You should have practiced the latter, without neglecting the former. . . . You are like whitewashed tombs, which look beautiful on the outside but on the inside are full of dead men’s bones and everything unclean. In the same way, on the outside you appear to people as righteous but on the inside you are full of hypocrisy and wickedness—Jesus Christ, Matthew 23:23, 27b-28. Certainly there are many appropriate, technical words for what Christianity means, and what Jesus in His death and resurrection has offered us; words like justification, sanctification, atonement, redemption and the like are appropriate to be studied and understood. But in the same way, psychologists and psychiatrists have doubtless written many books and theses on the dynamics of human relationships and friendships. But when you are in the middle of it, simply enjoying your relationship with your best friend, the technical terms are irrelevant, even while they are ongoing. You are just doing what best friends do: spending time together, getting to know each other, growing closer. That’s what Jesus came to establish between us and the Father. His desire is not the academic pursuit of understanding. His desire is that we are placed in the middle of that relationship. That’s all that matters.
