 Christadelphians believe that no one goes to Heaven upon death or go to purgatory.Instead, they believe that only Christ Jesus went to Heaven, and when he comes back to the earth only then will there be a resurrection of the saints, and God's kingdom will be established.Christadelphians believe these doctrines were introduced into Christendom after the 1st century in large part through exposure to pagan philosophy, and cannot be substantiated from the Biblical texts.
