The Liturgists are a group of people that were raised, and a few even became famous, in the Christian faith. They have since rejected their faith in Christ and now have a podcast and ministry* to discuss reality and truth in light of what they once believed.
Heavily, it's a reaction against their former worldview. It's spirituality without Christian terminology but with the goal of "deconstructing" with no intention of reconstructing to find reality and live by that.
A recent podcast episode they had was about swapping fundamentalism. The woman they interviewed talked of growing up in the church, her father a worship leader, and going on mission trips and church planting, the whole gamut. Then, she moved to L.A. and found herself among Eastern religions, practicing yoga, using crystals, and that whole gamut. In getting deeper into her new friends' practices, she realized they were as "fundamental" with strict rules and, specifically, roundabout explanations of how sex should be. The hosts and interviewee talked about how so many religions have power over their adherents by controlling the expectations and dialogue of sex and death. I see some truth to that.
I believe that the Christian faith is unique among all other worldviews and religions. It's distinct in that it is derived from the one and true living God. With that premise, all other religions are false and man-made. Any organized religion (and critical thinker for that matter) must grapple with the biggest questions of life: where we came from, why we are here, and what happens when we die. Even scientific, non-religious atheists have to consider this. Critical thinkers and devout adherents allow the answers to these questions to dictate how they live their lives. Discovering your beliefs is its own process, and that's where people clash the most, aside from where they arrive.
In swapping one worldview for another, people think one code is superior to the other. Maybe because it's opposite of their previous, or it logically makes more sense, or they like what it looks like, or other reasons. But that's the difference between a religion and a relationship. Only true, biblical Christianity offers a personal and fully loving, fully just relationship with its God, Jesus. All else out there, even nones (no religion), have a moral code or ethic that they live by. Because all religions (besides Christianity) come from man-made inspiration, they seek to gain followers by offering hope in explaining death and the beginning of life and tangible explanations of how to live. Christianity differs in that. People like the Liturgists naturally equate God with a burn or hurt they've had, or they misunderstand something about God's character.
Speakers on the Liturgists, I believe, have rejected their evangelical faith and seek another truth because they never experienced a true relationship with Christ in the beginning. Logic can be a great tool in the process of elimination in seeking truth, but conviction and understanding take faith, which I think is too intangible for many, which is the point of it.
*Ministry is the Christian word for it. It's a podcast and online forum and music and the like aimed at engaging critical thinkers and like-minded "recovering evangelicals" to discuss where they came from, what brought them to where they are now, and what they believe now.
