There is an Energy called Love that underlies all of existence. This Energy is not a supernatural being but a creative force that pulls us toward loving relationship and becoming our best selves both as individuals but also as a universal whole encompassing all of creation.
This Energy, fundamentally creative and relational, exploded forth into experience and eventually evolved humanity – a self-awareness.
Everything is created from this Energy or, we might say, is at least connected to it. However, human beings are aware of this connection at least at an unconscious level. It is this awareness that gives us our inherent drive to create meaning in our lives and our innate tendency toward spirituality.
Because we are aware at some level of our true nature, we know that our natural state is to be in unity or in harmony with this Energy. We are, at our best, lovingly creative and relational creatures always co-evolving toward a better whole (loosely defining “better” as more loving, happy, peaceful, compassionate, supportive, just, etc.).
However, having a consciousness of purpose, humans can misunderstand their purpose or even intentionally act against their purpose because with consciousness of purpose also comes free will. If we act at odds with the Energy of Love that is our true nature, acting out in violence and selfishness, for example, then we enter into a state of estrangement and can experience guilt and shame and further try to hide from our true selves. Our lives become marked with fear and anxiety. To find happiness, healing and wholeness, we have to reconnect ourselves to the Energy of Love.
Religion is a frame work of stories, language and ritual through which groups of people can share common ideas and experiences to help them on their journey to reconnect. Just like anything else, religions can be corrupted to act contrary to the Energy of Love.
How this affects some Christian ideas
God is not really moral or immoral, just or unjust – those are categories we created to help us think about what behaviors better align with Love (or don’t) as we try to reconnect with our true nature.
Humanity created sin and evil through exercise of our free will. They are only “in” God because we put them there. If you really want to blame God for evil, one could say that God gave us the option of free will knowing evil was the inevitable result. Or, if you don’t believe in free will, then nothing matters and of course everything is on God’s shoulders.
Sex and the body or in no way evil or sinful as long as they are not used counter to the Energy of Love. Enjoyed ethically (i.e. safely, consensually, with good communication, etc.) sex is a gift to be enjoyed. And I don’t see any reason it needs to be restricted to marriage or procreation, either. I mention communication as part of the ethics because perhaps it is the people involved that need to be defining the proper boundaries and not other people.
Jesus did not die “paying” for our sins. Jesus died trying to show us the path back to God. People killed him because he was a threat to their selfishness.
Hell is not a place but is the manifestation of our fear that we will not be able to reconnect to Love.
