Christianity died when they formed dogmas and ideologies. Imagine you are walking in an absolutely dark unfamiliar, unknown room. You will have your hands stretched outside and will touch everything on the way. Truth is beyond the human mind. Knowledge of God can be grasped, but understanding will be limited, as if scratching the surface. There are no words on the planet that can describe meanings that have never been understood by humans. Ideas are the walls, objects on the way. You don’t know the full picture, but it gives you a sense of direction. If an idea becomes dogma, you become attached to it, or even become trapped inside of it like in the box. You can't move anymore. Everything must be treated as a temporary understanding on the way of achieving global understanding. God accepts our misinterpretations. We need some orientation in the darkness. When you become enlightened, God's Spirit is calling you, you see those objects and walls and you naturally won't attach yourself to them. You walk more freely but still can be trapped inside of a wall if it becomes dogma. You will stop walking. And the people who don't have a source of light after you disappear will be stuck forever. God allows different ideas and understanding as long as you are not attached to them. You can believe in trinity or reincarnation as an abstract explanation of what you currently think is true. We all will get better explanations in the future, just keep going. Having an idea, keep in mind the simple honest truth - you don't know. Treat everyone on their journey to liberation and further as Jesus said - whoever is not against us is for us. The only thing that matters is guidance - the Holy Spirit, Holy Reason, Atman or any other name for the same entity. To get it, the ego must die through repentance, self denial and detachment from your feelings and thoughts, and surrender to God. After sensing that Spirit it will replace your feelings and thoughts and will become your guidance like a light. Eventually, this Spirit will become you. This is the transformation.
The moment an idea hardens into dogma, it stops being a helpful pointer and becomes a prison. Christianity, like any living tradition, was never meant to be a closed system of propositions to defend at all costs. At its core—especially in the teachings of Jesus—it's an invitation to a relationship, a journey, a dying to self so that something greater can live through us.
The tragedy is when people mistake the map for the territory. The Trinity, the atonement theories, the sacraments, the scriptures themselves—they're all fingers pointing at the moon. Useful, even beautiful, as long as we don't confuse the finger for the moon itself. When we do, we stop walking. We build walls out of what were once open doors.
God is not threatened by our incomplete understandings. The Spirit blows where it wills. Reincarnation in one tradition, resurrection in another, purgatory or karma or divine mercy—they may all be partial glimpses of the same mystery seen from different angles in the dark.
The key, is to hold every idea lightly. To walk humbly. To treat every doctrine as a temporary raft for crossing the river, not as a permanent home. And most importantly: to keep moving toward love, toward surrender, toward that Light that eventually doesn't just guide us but becomes us. In the end, the Spirit recognizes itself in others, even when the forms look different.
