Not at all. Since the church recognizes the complete sum of all experiential creation as its central deity, it merely provides the space to worship your deity (or deities) and all they have created without ever feeling in conflict. From Buddhism to Catholicism, there is virtually no conflicting barrier with any other world religion. As long as you desire to observe and practice the four core values, you may worship any deity you choose, attend any service you like, live any lifestyle you wish and still be a valuable member of the church.
The church prefers the term Grace, and recognizes the entirety of existence as divine. The church seeks to know that divinity without confusion, fear or judgement. This includes all universal existence, whether animate or inanimate, visible or invisible, thought, felt, or otherwise sensed. This means the church views all things, even those only subjectively perceived such as beliefs, deities, thoughts or feelings as Grace (or God, if you prefer).
It sure does! Church membership is not in any way limited to anyone, and is completely voluntary and free of charge. The only requirement for membership is a desire to observe the four core values in one's life and practice adhering to them: unconditional forgiveness and humility, the relentless pursuit of peace, self-care and sovereignty, community and charity.
The tenets are there to define the church as an entity, and to serve as an example for one's own self-definition. They are recognitional guidelines which only the church itself is held to, and are never forced on or expected of any member.
The church seeks to understand Grace to the best of its ability, and this means seeing through naturally deceptive and potentially frightening barriers. The least resistant path to accomplishing this is through a searching and fearless skeptical analysis of as much data as is conceivable. This does not make the church "scientific", but it does mean it approaches spirituality with a scientific methodology as cautiously and courageously as possible. It does this by observing thermodynamic law as a foundation for understanding universal order but never limiting it to physically measurable thermodynamics, and by never defending its position, but always being willing to consider any data and evolve based on new realization.
