"For God so loved the world that he gave his only Son, so that everyone who believes in him may not perish but may have eternal life. Indeed, God did not send the Son into the world to condemn the world, but in order that the world might be saved through him. Those who believe in him are not condemned; but those who do not believe are condemned already, because they have not believed in the name of the only Son of God" (John 3:16-18).
Unity appears to believe that salvation is not necessary in order to enter the kingdom of heaven. Does Unity believe that Jesus died for our sins? If not, what does Unity believe in this regard? I am a member of a Unity church, which is why this topic matters so much to me.
The central question, of course, is: What is meant by "his only Son"? Traditional Christians believe it can only refer to Jesus, but metaphysically the reference is to the Christ, which is the true identity of each of us. It is as the Christ that each of us is empowered to "save" the world by standing firm in this spiritual Truth, for ourselves and for others. "Those who do not believe" in their own spiritual power need to be "saved" from their own error thought, because they are choosing to live without that belief in themselves as "the only Son of God."
As for Jesus "dying for our sins," it is more accurate to recognize that Jesus went through the illusion of death to establish for all of us that we are immortal spiritual beings who can never be limited by the concept of death.
I'm sure that your own Unity center can be very helpful in answering your questions.
