Quite a lot of modern spiritual interpreters have a hidden dislike for Jesus. They secretly hate him. And I know you've noticed this too.
They venerate occult writers that served questionable agendas in this or that society, or very niche and strangely morally neutral personas throughout history, but they will always (as if by design) underestimate or underplay the meaning of sacrifice and unconditional love.
They find these ideas unfit for serious consideration. They find them unintellectual or not self-serving enough.
They will connect and align heavily with characters like Manly Hall, or venerate introductory manuscripts like the Kybalion, barely scratching the true depths of spiritual bliss.
They do this because the teachings provided by these manuscripts allow them to become excessively self-aggrandising or self-centric without feeling responsible for the grander good. And they have a tendency to see Christians (or those that hold belief in specific religious ideals) as less, or brainwashed, or "NPCs".
My opinion is that if you fail to understand the great allegory of Jesus' life path, you have a long way to go in finding yourself. If you ever were on a path of your own, one of humanity and pure spiritual scholarship, that is.
When you fail to mention Jesus or God in conversation and have to indirectly address him (as the "prime creator", or the "great architect", the "omnipotent all", etc) - there is a deep, inlaid fear within you, and those with heightened intuitive sense will never miss this little detail.
It will always be noticed, questioned and scrutinised.
Not being a staunch follower of this or that particular faith myself, this has always mystified me. The God or Messiah who has many enemies, with those same ones showing visible discomfort at the mention of his name - it makes you think, does it not?
