The website universalsalvation.org was an outreach of the UK-based Christianworld Church headed by the late Tony Sharpe that published occasional posts promoting the doctrine of Universalism after Sharpe’s death from a failed heart surgery in June 2004 until some time in 2016. The website does not specifically credit the articles there to Sharpe, but they appear to represent his views on scripture.
Like many other defunct websites, we only find Universal Salvation in The Wayback Machine’s archives. I can think of several possible reasons it is no longer active: (1) the church disbanded; (2) the person who maintained the blog died, as will happen to us all at one point, and subsequently discovered his beliefs did not represent reality; or (3) the person who maintained the blog discovered his error in this life and deleted it (we can only hope).
Either way, we don’t need to caution anybody at Universal Salvation about proof-texting. The same cannot be said for its former readers.
